Suppose an object moves along the y axis so that its location is yequalsf(x)equalsxsquaredplusx 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 2 to 5. (b) the average velocity for x changing from 2 to 2plush. (c) the instantaneous velocity at xequals2 second. (a) the average velocity is 8 m/sec. (b) the average velocity is (nothing )m/sec. (c) the instantaneous velocity is 5 m/sec.
