What do rumors and wildfires have in common? They are two things that can fan out rapidly, even wildly, over time. Rumors and wildfires are also examples of two things that can be described by exponential functions. They grow exponentially. Imagine that the math department at your school is going to be holding a math competition and each member of your class is required to submit a problem that involves exponential growth or decay. First, you will need to research or invent a situation that involves exponential growth or decay. If you find information on the Internet, remember that you must credit your source by using correct citations. Next, write up the problem and its solution, as they would appear in the competition handbook. Throughout this task, remember that you are trying to create an imaginative application of exponential functions for your classmates. The situation and the math involved can be as complicated as you wish it to be. The write-up should include: 2  A clear description of the situation  All assumptions that are made concerning the initial population and growth rate, and other elements of the situation if necessary  Use written and visual information to tell a compelling story  A detailed solution to the problem
