Question

Which represents exponential decay

Answer 1

Answer:

A represents exponential decay since it's the only answer with an exponent greater than 1.

Answer 2

A simple example is the function f(x)=2x. 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.
