Consider the function below. x -1 0 1 2 f(x) -2 3 8 13 which of the following functions could be the inverse of function f? x -2 3 8 13 q(x) -1 0 1 2 x -2 -3 -8 -13 r(x) 1 0 -1 -2 x -1 0 1 2 p(x) 2 -3 -8 -13 x 1 0 -1 -2 s(x) -2 3 8 13

David estimated he had about 20 fish in his pond. a year later, there were about 1.5 times as many fish. the year after that, the number of fish increased by a factor of 1.5 again. the number of fish is modeled by f(x)=20(1.5)^x. create a question you could ask that could be answered only by graphing or using a logarithm.
