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.
