Question

Find the zeros of the function: f(x)=−x 3+9x 2 −12x−22

How many total zeros are you looking for?

A. 1

B. 2

C. 3

D. 0

Answer 1

To find the zeros of the function, we set it equal to zero and solve for x. The correct answer is 2 zeros.

Step-by-step explanation:

In order to find the zeros of the function, we need to set the function equal to zero and solve for x.

So, we have the equation -x^3 + 9x^2 - 12x - 22 = 0.

To solve this equation, we can use various methods such as factoring, synthetic division, or the rational root theorem.

After finding the zeros, we can determine the number of total zeros by counting the number of distinct solutions we obtained.

Therefore, the correct answer is B. 2
