Using the graph of g ' shown below and the fact that g(0) = 50, find the coordinates of all the critical points and inflection points of g. (20, 10) 15 40 -10 (10, -20) (a) The critical points of g occur at what points? ( 15 x ) (smaller x value) ) (larger x value) (b) The inflection points of g occur at what points? ) (smaller x value) ) (larger x value)
