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