Question

The function f(x)=-x^2-2x+15 is shown on the graph. What are the domain and range of the function?

Answer 1

2nd choice down

Explanation:

Domain is the set of all real numbers (no restrictions on x).

The vertex of the solid-line open-down parabola is at (-1, 16), therefore the range is y≤16 (maximum value of y is 16, at the vertex point (-1, 16). Range is y
