The graph of the function f (x) = - (x + 6) (x + 2) is shown below.

On a coordinate plane, a parabola opens down. It goes through (negative 6, 0), has a vertex at (negative 4, 4), and goes through (negative 2, 0).

Which statement about the function is true?

The function is increasing for all real values of x where

x < - 4.

The function is increasing for all real values of x where

-6 < x < - 2.

The function is decreasing for all real values of x where

x - 2.

The function is decreasing for all real values of x where

x < - 4.
