Some bullfrogs were introduced into a small pond. The graph shows the bullfrog population for the next few years. Assume that the population grows exponentially. nA 700 600- Frog population 400- 500- 300- (2,225) 200 100 + + 0 1 2 3 4 5 6 t (a) What was the initial bullfrog population? 100 bullfrogs (b) Find a function that models the bullfrog population t years since the bullfrogs were put into the pond.
