When bacteria infect an animal, the number of bacteria in the body increases in an exponential fashion (graph A). After infection by a virulent animal virus with a lytic replicative cycle, there is no evidence of infection for a while. Later, however, the number of viruses rises suddenly and subsequently increases in a series of steps (graph B). Explain the difference in the curves.

Bacteria Growth A certain type of bacteria increases according to the model $P(t)=100 e^{0.2197 t},$ where $t$ is the time in hours. (a) Use a graphing utility to graph the model. (b) Use a graphing utility to approximate $P(0), P(5),$ and $P(10) .$ (c) Verify your answers in part (b) algebraically.
