Suppose an object moves along the y axis so that its location is y = f(x) = x + x at time x (y is in meters, x is in seconds). Find (A) The average velocity (the average rate of change of y with respect to x) for x changing from 3 to 7. (B) The average velocity for x changing from 3 to 3 + h. (C) The instantaneous velocity at x = 3 second. . . . (A) The average velocity is m/sec. (B) The average velocity is m/sec. (C) The instantaneous velocity is m/sec
