The fox population in a certain region has an annual growth
rate of 7 percent per year. It is estimated that the
population in the year 2000 was 12500.
(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.
