Consider the family of functions given by h(t) = a where a > 0 and b > 0. (a) Find h '(t) = (b) Find the tcoordinates of the critical points of h(t). t = (smaller) t = (larger) (c) Find the tcoordinates of the global maximum and global minimum of h(t) on the interval 0 s t 5 7b. If there is no global maximum or no global minimum, write NONE. t = (global maximum) t = (global minimum)
