Question

The graph of the function f(x) = –(x + 3)(x – 1) is shown below.

On a coordinate plane, a parabola opens down. It goes through (negative 3, 0), has a vertex at (negative 1, 4), and goes through (1, 0).

Which statement about the function is true?

The function is positive for all real values of x where
x < –1.
The function is negative for all real values of x where
x < –3 and where x > 1.
The function is positive for all real values of x where
x > 0.
The function is negative for all real values of x where
x < –3 or x > –1.

Answer 1

the answer is B

Explanation:

YW

Answer 2

It opens downward and crosses the x axis at (-3,0) and (1,0) this means for any x value less than -3 or greater than 1, the function is negative.

The answer would be:

The function is negative for all real values of x where

x < –3 and where x > 1.
