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

The answer is D, (x + 1) (x + 2) (x - 3)

Answer 2

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

Explanation:

The x-intercepts help us to form the equation of the curve:

(-2, 0) (-1, 0) and (3, 0)

--> x = -2, x = -1, x = 3

--> x + 2 = 0 x + 1 = 0 x - 3 = 0

--> (x + 2) × (x + 1) × (x - 3) = 0

This is the reverse order for the Zero Product Property
