Scientists studying a population of endangered bats find that the population is decreasing by 16% per year. The current population size is 1,800. What function models the number of years, f(n) , it will take the population to reach a size of n individuals?

Replace the values of a and b in the equation to create the model.

Answer:f(n) = 1800(1-0.16)^n= 1800(0.84)^n
