On a coordinate plane, a parabola opens down. It has an x-intercept at (negative 5, 0), a vertex at (negative 1, 16), a y-intercept at (0, 15), and an x-intercept at (3, 0). The function f(x) = –x2 − 2x + 15 is shown on the graph. What are the domain and range of the function? The domain is all real numbers. The range is y < 16. The domain is all real numbers. The range is y ≤ 16. The domain is x. The range is y < 16. The domain is –5 ≤ x ≤ 3. The range is y ≤ 16.
