Question

PLEASE HELP ASAP!!! CORRECT ANSWERS 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

Explanation:

The x-intercepts of the graph are: x = -2 , x = -1, and x = 3

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

--> (x + 2) (x + 1) (x - 3)
