- The fox population in a certain region has an annual growth rate of 8 percent per year. It is estimated that the population in the year 2000 was 22600. (a) Find a function that models the population t years after 2000 (t = 0 for 2000). Your answer is P(t) = (b) Use the function from part (a) to estimate the fox population in the year 2008.
