Question

PLEASE HELP ASAP!!! CORRECT ANSWER ONLY PLEASE!!!

The graph of the function f(x) = x^3 – 7x – 6 intersects the x-axis at the points (–2, 0), (–1, 0), and (3, 0) as shown.

Which expression is equivalent to x^3 – 7x – 6?

Answer 1

Answer: D) (x + 1)(x + 2)(x - 3)

Explanation:

The x-intercepts are given as x = -2, x = -1, and x = 3

x = -2 --> x + 2 = 0

x = -1 --> x + 1 = 0

x = 3 --> x - 3 = 0

The factors of the equation are: (x + 2)(x + 1)(x - 3) = 0
