EXPONENTIAL GROWTH
AND DECAY
In this unit, we will look at a variety of applications that are modeled by logarithmic and exponential functions. Exponential and logarithmic functions model many scientific phenomena. Some applications of exponential functions include population growth, compound interest, and radioactive decay. Radioactive decay is used to date ancient objects found at archeological sites. Applications of logarithmic functions include the pH scale in chemistry, sound intensity, and Newton’s law of cooling.
