62. MOTORCYCLE DEATHS Suppose the fatality rate (deaths per 100 million miles traveled) of motorcyclists is given by g(x), where x is the percentage of motorcyclists who wear helmets. Next, suppose the percentage of motorcyclists who wear helmets at time t ( t measured in years ) is f(t), with t = 0 corresponding to 2000. a. If f(0) = 0.64 and g(0.64) = 26, find (go f ) (0) and interpret your result. b. If f(6) = 0.51 and g(0.51) = 42, find (go f) (6) and interpret your result. c. Comment on the results of parts (a) and (b). Source: National Highway Traffic Safety Administration
