The following graph shows the total number n of people (in millions) infected in an epidemic as a function of time t (in years). (Assume a = 9.) (a) When to the nearest year was the rate of new infection largest?
[removed] year(s) into the epidemic

(b) When could the Centers for Disease Control and Prevention announce that the rate of new infection was beginning to drop? HINT [See Example 4.]
[removed] year(s) into the epidemic
