WebAn exponential decay equality models many chemical and biological processes. It is used whenever the rate at which something done is proportional to the amount which is left. Here are three examples: Radioactive decay data tables (Technical Report) OSTI.GOV WebAn exponential function can describe growth or decay. The function. g ( x) = ( 1 2) x. is an example of exponential decay. It gets rapidly smaller as x increases, as illustrated by its graph. In the exponential growth of f ( x), the function doubles every time you add one to its input x. In the exponential decay of g ( x), the function shrinks ...
