Suppose that the function fhas a continuous second derivative for all x, and that fo) = 2, f(0) = -1, and f(0) = 0. Let gbe a function whose derivative is given by g'(x) = e3x (f(x) + 2F(x)) for all x. Does g have a local maximum, local minimum, or neither at x = 0? Justify your answer.

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.
