Exponential growth and decay
An exponential growth or decay model makes a quantity’s instantaneous rate proportional to the quantity itself. The differential equation y′=ky gives y=Ceᵏˣ, with positive k describing growth and negative k describing decay for positive y. For example, a population with a constant relative growth rate doubles in equal time intervals. Its relative rate stays constant, while its absolute rate changes with the amount present.
