A sculptor creates an arch in the shape of a parabola. When sketched onto a coordinate grid, the function f(x) = –2(x)(x – 8) represents the height of the arch, in inches, as a function of the distance from the left side of the arch, x. What is the height of the arch, measured 3 inches from the left side of the arch?

14 inches
15 inches
28 inches
30 inches

f(3) = -2(3)(3 - 8) = -2(3)(-5) = 30.

So the height is 30 inches.
