A species of animal is discovered on an island. Suppose that the population sizeP(t)

of the species can be modeled by the following function, where timet

is measured in years.

P(t)=450/1+9e^-0.3t

Find the population size after5

years and after8

years.

Round to the nearest whole number as necessary.

Population size after 5 years: _____individuals

Population size after 8 years: _____individuals
