Suppose an object moves along the y axis so that its location is y = f(x) = x^2 + 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 1 to 3. (B) The average velocity for x changing from 1 to 1 + h. (C) The instantaneous velocity at x = 1 second. (A) The average velocity is m/sec. (B) The average velocity is m/sec. (C) The instantaneous velocity is m/sec.

Suppose that an object moves along the y-axis so that its location is y = x^2 + 7x at time x. (Here y is in meters and x is in seconds). a) Find the average velocity (the average rate of change of y with respect to x) for the interval from 2 to 9 seconds. Don't forget to include units in all your answers. b) Find the average velocity for x changing from 5 to 5 + h seconds. c) Find the instantaneous velocity at x = 5 seconds.
