Exponential and Logarithmic Functions
Exponential Functions are used to model growth of populations, interest on an investment, depreciation of cars, decay of radioactivity, and many other real-life things. Logarithmic Functions are used to measure earthquakes (Richter Scale), Acidity (pH), and Sound Intensity (decibels).
BioMath Applications
Biology presents many opportunities to model real-life applications with exponential and logarithmic functions. Read the examples and do the problems from the University of Arizona's BioMath web-site.
