This document may be used with interactive direct teaching, as a worksheet, or as a review. It is especially useful for students who catch on to mathematics easily but may be used with any students. It is considered "no nonsense" because, within two pages, both exponential growth and decay and their equations are introduced. The document has three "real-world" problems so that the students can see where exponential functions may be represented in the real world. This document has been prepared by Susan M. Walker.
