Question

WILL MARK BRAINLIEST!!! PLZ HELP!!! Which graph best represents the function f(x) = (x + 1)(x − 1)(x − 4)? I think it's D, but im not sure

Answer 1

Answer:

D

Step-by-step explanation:

Find the x intercepts from the equation and apply them to the graphs. It matches up with D. Your thought is correct

Answer 2

Answer:

$\boxed{\mathrm{D}}$

Step-by-step explanation:

$y= (x + 1)(x - 1)(x - 4)$

Let x = 0, find the y-intercept.

$y= (0 + 1)(0 - 1)(0 - 4)$

$y= ( 1)(- 1)(- 4)$

$y=4$

The function crosses the y-axis at 4.

The only graph that shows this is graph D.
