Question

Which of the following is an x-intercept of the function, f(x)=x^3-x^2-8x+12?

A. 4
B.-3
C.3
D.-4

Answer 1

-3

Explanation:

Just took it

Answer 2

Option B.-3

Explanation:

we know that

An x-intercept is a value of x when the value of the function f(x) is equal to zero

we have

`f(x)=x^(3)-x^(2)-8x+12`

Determine the roots of the function f(x) by graphing

using a graphing tool

The roots are x=-3, x=2
