When the zombie apocalypse comes, the mathematicians will be the only ones safe, primarily because they, like modern day epidemiologists, understand that the rate of transmission is modeled by a function that is not based on a polynomial. A different type of function models growth and decay of populations: the exponential function. Exponential functions are extremely useful for modeling anything that grows or decays over time:

- populations
- money
- the metabolism of chemicals in your bloodstream
- the list goes on!

Today, we will find out some of the basic characteristics of exponential functions.
