3) The population of a town increased from 3500 in 2010 to 4100 in 2017. Let x = 0 for year 2010. a) (6 pts) Build a model exponential function of the form P(t) = P oekt for the population of this town. Clearly show your algebraic work. b) (4 pts) Use your answer from part (a) to predict the year when the town's population will reach 7000. Clearly show your algebraic work.
