Exponential Function
Exponential Model

A function of the form y = a·b^x where a > 0 and either 0 < b < 1 or b > 1. The variables do not have to be x and y. For example, A = 3.2·(1.02)^t  is an exponential function.

Note: Exponential functions are used to model exponential growth, exponential decay, compound interest, and continuously compounded interest.
