Kevin is observing the population of the fish he put into a pond. he built a pond and populated it with 500 fish. the population of the fish doubles every year. use x to represent the number of years and y to represent the population of the fish. enter an equation that represents this scenario in the box.

Given that the number of years should be represented with x, the number of fish in the pond after x years should best be represented with f(x). The equation that would best show the given scenario in the problem above is,
                             f(x) = 500(2^x)
From the given, 500 is used as the initial population of the fish.
