Chapter 4, Problem 4.2.3(choose chapter or problem)
The following formulas give the populations (in 1000s) of four different cities, A, B, C, and D, where t is in years. Which are changing exponentially? Describe in words how each of these populations is changing over time. Graph those that are exponential. PA = 200 + 1.3t, PB = 270(1.021)t , PC = 150(1.045)t , PD = 600(0.978)t .
