The function f(x) = 5x2 describes the volume of a rectangular box, f(x), in cubic inches, whose square base has sides that each measure x inches and whose height is 5 inches. If x is changing, a. Find the average rate of change of the volume with respect to x as x changes from 2 inches to 2.1 inches and from 2 inches to 2.01 inches. b. Find the instantaneous rate of change of the volume with respect to x at the moment when x = 2 inches.
