Exponential functions are often used for modeling population growth, as we see in these examples. The function notation shows that you're modeling a population in terms of the input, time. Pay attention to the units because these problems are often presented "in thousands of individual" or perhaps "per decade." Most errors come from typing these into your calculator incorrectly use parentheses or do it in parts according to the order of operations if necessary.
