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) = βx2 β 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|y < 16}.
The domain is all real numbers. The range is {y|y β€ 16}.
The domain is {x|β5 < x < 3}. The range is {y|y < 16}.
The domain is {x|β5 β€ x β€ 3}. The range is {y|y β€ 16}.
