# Exponential Functions: Exponential Decay

This packet helps students understand how exponential decay works. Each page starts with easier problems that get more difficult as students work through the packet. After doing all 16 problems, students should be more comfortable doing these problems and have a clear understanding of how to solve them.

Simple: *Identify the initial amount and decay factor in the following exponential functions.* y = 100(.03)^{x}

Advanced: *After buying a used Honda for $8,000, it depreciated 4% per year. Find the value of this car after the given number of years.* 2 years **=**

Practice problems require knowledge of exponents.
