A town with a population of 12 000 has been growing at an average rate of 2.5% for the last 10 years. Suppose this growth rate will be maintained in the future. The function that models the town's growth is P(n) = 12(1.025") where P(n) represents the population (in thousands) and n is the number of years from now. a) Determine the population of the town in 10 years. b) Determine the number of years until the population doubles. c) Use this equation (or another method) to determine the number of years ago that the population was 8000. Answer to the nearest year. d) What are the domain and range of the function?
