Let f(x)=x² -3x+5. Show that the average rate of change of f (with respect to x) on an arbitrary interval [a , b] is equal to the instantaneous rate of change of f at the midpoint of that interval. Show and explain your work. (Note: This will be true for any quadratic function, and not just for the given one.)
