Work will not be checked on these problems, so you will need to take care in marking your solutions. Find c and depict this graphically. f (c) = . 5: suppose that f (x) is continuous on the interval [2, 5] and di erentiable on the interval (2, 5). Show that if 1 f (x) 4 for all x [2, 5], then 3 f (5) f (2) 12. For the function de ned in (a) nd the intervals on which f is concave up and the intervals on which f is concave down. For the function f (x) = x1/3(1 x)2/3, Nd the intervals on which f is increasing and the intervals on which f is decreasing.
