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 < –6 and where x > –2.
the function is decreasing for all real values of x where
x < –4.
