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).
The Exponential Growth/Decay Equation
The exponential growth/decay equation is y = abx, see notes below.
