2. The population of a small town is modelled by the function thousands, and t is time, in years, since the start of 2005. P(t) = 20(4t+ 3) 2t+5 a) Is the population currently increasing or decreasing? Justify your answer. where P(t) is the population, in b) The town will need its own transit system if the population exceeds 50 000. Will the town's population exceed 50 000? Explain.
