Don has been tracking the population of a town. The population was 7,220 last year and has been increasing by 1.45 times each year. How can Don develop a function to model this? f (x) = (7220 • 1.45) x where 1.45 is the rate of growth f (x) = 1.

What would happen to the graph of f (x) = 2 (x-5) ^2 if you change the a value to - 2?
