Suppose an object moves along the y axis so that its location is y=f(x)=xsquared+x at time x(y is inmeters, x is inseconds). Find

(A) The average velocity(the average rate of change of y with respect tox) for x changing from 2to 5.

(B) The average velocity for x changing from 2to 2plus+h.

(C) The instantaneous velocity at x=2second.

(A) The average velocity is?gm/sec.

(B) The average velocity is? ()m/sec.

(C) The instantaneous velocity is?m/sec.
