In Problem, suppose an object moves along the y axis so that its location is y = f(x) = x2 + x at time x (y is in meters and x is in seconds). Find
(A)The average velocity (the average rate of change of y with respect to x) for x changing from 2 to 4 seconds
(B) The average velocity for x changing from 2 to 2 + h seconds
(C) The instantaneous velocity at x = 2 seconds
