The graph of the function f (x) = (x + 2) (x - 4) is shown.

On a coordinate plane, a parabola opens up. It goes through (negative 2, 0), has a vertex at (1, negative 9), and goes through (4, 0).

Which describes all of the values for which the graph is negative and increasing?

all real values of x where x < - 2

all real values of x where - 2 < x < 4

all real values of x where 1 < x < 4

all real values of x where x < 0
