et
P = f(t) =
10+ e
0<t< 5,
gives the fraction of the population of a town infected with a virus at time t,
where t is the number of months since the start of the year 2021.
(a) Draw an accurate graph of the function P = f(t). Use technology to
help.
(b) What are the units of the derivative dP/dt?
(c) Suppose the town has a population of 540, 000. At what rate is the
virus spreading at the start of 2021?
