Modeling with Trigonometric Functions · Review Exercise 113

Model the described behavior and find requested values.

The native fish population of Lake Freshwater averages 2500 fish, varying by 100 fish seasonally. Due to competition for resources from the invasive carp, the native fish population is expected to decrease by 5% each year. Find a function modeling the population of native fish with respect to the number of years from now. Also determine how many years it will take for the carp to overtake the native fish population.
