Type I Rewrite both sides of using same base Cancel bases Set the exponents equal and solve Solve Solve Answer Rewrite cancel bases solve Solve Solve Answer Rewrite cancel bases solve. After linear functions the second most important class of functions are what are known as the exponential functions Population growth in64258ation and radioactive decay are but a few examples of the various phenomenon that exponential functions can How long will it take the population to reach 5000 people? e) What is the doubling time of the population? Solution: a) Since P(0) = 3200e0.0321(0) Since k = 0.0321, ! 3200(1.900277637) ! 6081 p Exponential Growth Functions.
