The graph of the function f(x) = (x + 2)(x + 6) is shown below.
On a coordinate plane, a parabola opens up. It goes through (negative 6, 0), has a vertex at (negative 4, negative 4), and goes through (negative 2, 0).
Which statement about the function is true?
The function is positive for all real values of x where
x > β4.
The function is negative for all real values of x where
β6 < x < β2.
The function is positive for all real values of x where
x < β6 or x > β3.
The function is negative for all real values of x where
x < β2.
