Which function represents a vertical stretch of an exponential function? fx)=3(1/2)x
f(x)=1/2(3)x
f(x)=(3)2x
f(x)=3(1/2x)

Create a question with this scenario you could ask that could be answered only by graphing or using logarithm. 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.
