Introduction

In mathematics, the study of functions and their graphs is a crucial aspect of understanding various mathematical concepts. One of the fundamental concepts in algebra is the study of polynomial functions and their graphs. In this article, we will explore the graph of the function f(x)=x3+x2−9x−9f(x)=x^3+x^2-9x-9 and determine the solutions of the equation x3+x2−9x−9=0x^3+x^2-9x-9=0 based on the graph.

Understanding the Graph of a Function

The graph of a function is a visual representation of the function's behavior. It is a powerful tool for understanding the properties of a function, such as its domain, range, and behavior at different points. In the case of the function f(x)=x3+x2−9x−9f(x)=x^3+x^2-9x-9, the graph is a cubic curve that has three distinct roots.

The Graph of f(x)=x3+x2−9x−9f(x)=x^3+x^2-9x-9

The graph of f(x)=x3+x2−9x−9f(x)=x^3+x^2-9x-9 is shown below:

From the graph, we can see that the function has three distinct roots, which are the points where the graph intersects the x-axis. These roots are the solutions of the equation x3+x2−9x−9=0x^3+x^2-9x-9=0.

Determining the Solutions of x3+x2−9x−9=0x^3+x^2-9x-9=0

To determine the solutions of the equation x3+x2−9x−9=0x^3+x^2-9x-9=0, we need to examine the graph and identify the points where the graph intersects the x-axis. From the graph, we can see that the function intersects the x-axis at three points: x=−3x=-3, x=−1x=-1, and x=3x=3.

Conclusion

Based on the graph of the function f(x)=x3+x2−9x−9f(x)=x^3+x^2-9x-9, we can conclude that the solutions of the equation x3+x2−9x−9=0x^3+x^2-9x-9=0 are x=−3x=-3, x=−1x=-1, and x=3x=3. Therefore, the correct answer is:

A. x=−1,3x=-1, 3

However, this is not the only possible answer. We can also consider the possibility that the graph intersects the x-axis at more than three points. In this case, the correct answer would be:

D. x=−9,−3,−1,3x=-9, -3, -1, 3

However, this is not supported by the graph, and we can conclude that the correct answer is indeed:

A. x=−1,3x=-1, 3

Discussion

The graph of a function is a powerful tool for understanding the properties of a function. In this article, we have seen how the graph of the function f(x)=x3+x2−9x−9f(x)=x^3+x^2-9x-9 can be used to determine the solutions of the equation x3+x2−9x−9=0x^3+x^2-9x-9=0. We have also seen how the graph can be used to identify the domain, range, and behavior of a function.

Final Answer

The final answer is:

A. x=−1,3x=-1, 3

However, it's worth noting that the other options are not entirely incorrect. The graph does intersect the x-axis at x=−3x=-3, and the equation x3+x2−9x−9=0x^3+x^2-9x-9=0 does have a root at x=−3x=-3. Therefore, the correct answer could also be:

B. x=−3,−1x=-3, -1

Or even:

C. x=−3,−1,3x=-3, -1, 3

But the most accurate answer based on the graph is:

A. x=−1,3x=-1, 3
