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 > –4.
the function is negative for all real values of x where
–6 < x < –2.
the function is positive for all real values of x where
x < –6 or x > –3.
the function is negative for all real values of x where
x < –2.

Harold wrote this equation to model the level of water in a pool over time. the variable x represents time in hours. f(x) = 3,500 - 225x which statements about the situation are true? check all that apply. the water level is rising. the water level is falling. the initial level of water in the pool was 3,500 units. the initial level of water in the pool was 225 units. the pool was empty after 14 hours. the water was 2,600 units high after 4 hours.
