The function f(x) = −(x + 5)(x + 1) is shown.

On a coordinate plane, a parabola opens down. It goes through (negative 5, 0), has a vertex at (negative 3, 4), and goes through (negative 1, 0).
What is the range of the function?

all real numbers less than or equal to 4
all real numbers less than or equal to −3
all real numbers greater than or equal to 4
all real numbers greater than or equal to −3

The parabola opens downward and has a maximum (vertex) at y = 4, so the function takes all values ≤ 4.

Answer: all real numbers less than or equal to 4 (range = (-∞, 4]).
