3. Consider the function hx) = a[2x + 1)5 b, where (1 0 and b at 0 are constants. A. Find h'(x) and h\"{x). {6 points) B. Show that h is monotonic {that is, that either h always increases or remains constant or n always decreases or remains constant). {12 points) C. Show that the xcoordinateis} of the |ocation(s] of the critical points are independent ofa and b. (12 points)
