Exponential and Logarithmic Functions
In order to solve equations that contain exponentials, we need logarithmic functions. Logarithmic functions are the inverses of exponential functions. The properties of logarithms are used frequently to help us simplify exponential functions. Logarithmic functions have a unique set of characteristics and asymptotic behavior, and their graphs can be easily recognized if we know what to look for.
