Have you ever wondered at which root the graph of F(x) = (x + 4)^6(x + 7)^5 crosses the X-axis? This question has been a topic of interest among mathematicians and students alike. The X-axis is a crucial part of any graph, representing the values of x where the function is equal to zero. Finding the roots of a function is essential in solving equations, and it can also help us understand the behavior of the function as it approaches these critical points.

To answer this question, we need to analyze the function and its properties. Firstly, we can determine that the function is a polynomial of degree 11, meaning it has 11 roots. However, not all of these roots will necessarily cross the X-axis. To find the roots that do, we need to set the function equal to zero and solve for x.

One way to approach this problem is by using a graphing calculator or software. By plotting the function on a coordinate plane, we can visually identify the points where the graph intersects the X-axis. This method is relatively straightforward and accurate, but it doesn't provide us with an exact solution.

Another approach is to use algebraic methods to solve for the roots analytically. This process can be more complex, but it gives us a precise answer. We can use techniques such as factoring, synthetic division, or the rational root theorem to simplify the equation and find the roots.

One important factor to consider when solving this problem is the multiplicity of the roots. The multiplicity represents the number of times a root appears in the function. For example, if a root has a multiplicity of two, it means that the function touches the X-axis at that point but doesn't cross it.

After analyzing the function, we can conclude that it has two distinct roots that cross the X-axis. The first root is -7, with a multiplicity of 5. This means that the graph touches the X-axis at (-7,0) but doesn't cross it. The second root is -4, with a multiplicity of 6. This root is the one we are looking for, as it crosses the X-axis at (-4,0).

In conclusion, finding the roots of a function is a crucial step in understanding its behavior and solving equations. The graph of F(x) = (x + 4)^6(x + 7)^5 crosses the X-axis at x = -4, with a multiplicity of 6. Whether through graphical or algebraic methods, solving for these critical points is essential in mathematics and its applications.

The Problem: Graphing F(X) = (X + 4)^6(X + 7)^5

As a student studying mathematics, graphing functions is an important tool to understand the behavior of equations. One such equation is f(x) = (x + 4)^6(x + 7)^5. The question at hand is where does this graph cross the x-axis? To solve this problem, we must first understand the function and its properties.

Understanding the Function

The function f(x) = (x + 4)^6(x + 7)^5 can be simplified as a polynomial of degree 11. This means that the graph of the function will have a total of 11 roots or x-intercepts. However, we are only concerned with where the graph crosses the x-axis, which means we are looking for the real roots of the function.

Real Roots

Real roots are values of x that make the function equal to zero. In other words, they are the points where the graph crosses the x-axis. To find the real roots of the function, we can use algebraic methods such as factoring, synthetic division, or the quadratic formula. However, in this case, factoring is the most efficient method.

Factoring the Function

To factor the function f(x) = (x + 4)^6(x + 7)^5, we can use the distributive property. We start by factoring out the common factor (x + 4)^5, which gives us:

f(x) = (x + 4)^5(x + 4)(x + 7)^5

We can further simplify this expression by factoring out another common factor (x + 7)^5, which gives us:

f(x) = (x + 4)^5(x + 7)^5(x + 4)(x + 7)

Roots of the Function

Now that we have factored the function, we can see that there are two distinct roots: x = -4 and x = -7. These are the two points where the graph of the function crosses the x-axis.

Plotting the Roots on a Graph

Now that we know the roots of the function, we can plot them on a graph to see where the graph crosses the x-axis. The roots x = -4 and x = -7 are plotted as points (-4, 0) and (-7, 0), respectively.

The Nature of the Roots

It is important to note that the roots x = -4 and x = -7 are both real and distinct. This means that the graph of the function f(x) = (x + 4)^6(x + 7)^5 will cross the x-axis at these two points, but will not touch or intersect the x-axis anywhere else.

Using Technology to Verify the Solution

To verify our solution, we can use technology such as a graphing calculator or a computer program to plot the function and see where it crosses the x-axis. By using technology, we can confirm that our answer of x = -4 and x = -7 is correct and that there are no other real roots.

Graphing the Function

When we graph the function f(x) = (x + 4)^6(x + 7)^5, we can see that the graph crosses the x-axis at x = -4 and x = -7. The graph also shows us that there are no other real roots of the function.

Conclusion

In conclusion, the graph of the function f(x) = (x + 4)^6(x + 7)^5 crosses the x-axis at x = -4 and x = -7. These are the only real roots of the function, and they are both distinct. By understanding the properties of the function and using algebraic methods such as factoring, we can easily find the answer to this problem. Additionally, by using technology to verify our solution, we can be confident that our answer is correct.

Understanding the Problem: F(X) = (X + 4)6(X + 7)5

When faced with a function such as F(X) = (X + 4)6(X + 7)5, it is important to first understand the problem at hand. This function represents a polynomial equation with two factors, each raised to a power. The degree of this function is 11, which means that it has 11 terms. To find the roots of this equation, we must determine where the graph of the function crosses the x-axis.

Graphing F(X): Identifying the Shape and Symmetry

Before we can determine where the graph of F(X) crosses the x-axis, we must first graph the function. By doing so, we can identify the shape and symmetry of the graph. Since the degree of this function is odd, we know that it will have a symmetry about the origin. Additionally, since the leading coefficient is positive, the graph will open upwards.

The X-Axis: Where Does it Cross the Graph of F(X)?

The x-axis represents the set of values for which F(X) = 0. Therefore, to determine where the graph of F(X) crosses the x-axis, we must solve for the roots of the equation. These roots will give us the values of X for which F(X) = 0.

Finding the Roots of F(X): Importance and Relevance

The roots of an equation are crucial in understanding the behavior of the graph. They represent the points at which the graph intersects the x-axis, and can provide insight into the overall shape and behavior of the function. Additionally, knowing the roots can help us solve real-world problems related to the function.

Using Algebra to Solve for the Roots of F(X)

To solve for the roots of F(X), we must set the equation equal to zero and solve for X. By doing so, we can find the values of X for which F(X) = 0. This can be done using algebraic techniques such as factoring or the quadratic formula.

Factoring F(X): An Alternative Method of Solving

One way to solve for the roots of F(X) is by factoring the equation. By factoring out common factors, we can simplify the equation and make it easier to solve. In this case, we can factor out (X + 4)5 to get (X + 4)5(X + 7)5 = 0. Then, we can set each factor equal to zero to find the roots.

Identifying the Leading Coefficient of F(X)

The leading coefficient of F(X) is the coefficient of the term with the highest degree. In this case, the leading coefficient is positive, which means that the graph of F(X) will open upwards.

At Which Root Does The Graph Of F(X) = (X + 4)6(X + 7)5 Cross The X-Axis?

The Story of the Graph's Roots

Once upon a time, there was a mathematical function called F(x) = (x + 4)6(x + 7)5. This function had a curious property - its graph would cross the x-axis at certain points, known as roots. But where exactly were these roots located?

To answer this question, we must turn to the graph itself. Looking at the graph of F(x), we can see that it has two distinct humps, one on the left-hand side and one on the right-hand side. These humps represent the factors (x + 4)6 and (x + 7)5, respectively.

Now, we know that a factor of a polynomial will be equal to zero when the variable is equal to the opposite of the constant term. In other words, (x + a) = 0 when x = -a. Applying this rule to our factors, we can find the roots of each one:

Roots of (x + 4)6

x = -4

Roots of (x + 7)5

x = -7

So, we have two roots: x = -4 and x = -7. But which one represents the point at which the graph of F(x) crosses the x-axis?

To answer this question, we must look at the behavior of the graph between these two roots. We know that the graph is positive to the left of x = -4, negative between x = -4 and x = -7, and positive again to the right of x = -7. This means that the graph must cross the x-axis at some point between x = -4 and x = -7. But where exactly?

This is where we must turn to calculus. By taking the derivative of F(x) and setting it equal to zero, we can find the critical points of the function. These critical points will give us the exact location of the root at which the graph crosses the x-axis.

After some calculation, we find that the critical point of F(x) is located at x ≈ -5.8. This means that the graph of F(x) crosses the x-axis at the point (x ≈ -5.8, 0).

The Point of View of the Roots

As we've seen, the roots of a polynomial function are crucial in determining the behavior of its graph. But what do these roots think about their role in the function?

If we imagine ourselves as one of the roots of F(x) = (x + 4)6(x + 7)5, we might feel a sense of pride knowing that our location has a direct impact on the shape of the graph. We might also feel a sense of responsibility, knowing that if we were to move even a little bit, the entire graph would be affected.

But ultimately, we would recognize that our role is just one small part of a larger equation. Each root works together with the others to create a complex and beautiful pattern that represents the function as a whole. And while we may not always understand the bigger picture, we can take comfort in knowing that we are an important piece of the puzzle.
