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).
What is true about the domain and range of the function?
The domain is all real numbers, and the range is all real numbers greater than or equal to - 4.
The domain is all real numbers greater than or equal to
-4, and the range is all real numbers.
The domain is all real numbers such that - 6 ≤ x ≤ - 2, and the range is all real numbers greater than or equal to - 4.
