### Understanding Exponential Decay Functions

In an exponential decay function, the base of the exponent is a value between 0 and 1. Thus, for some number \( b > 1 \), the exponential decay function can be written as:

\[ f(x) = a \cdot \left( \frac{1}{b} \right)^x. \]

Use this formula, along with the fact that \( b = e^n \), to show that an exponential decay function takes the form:

\[ f(x) = a(e)^{-nx} \]

for some positive number \( n \). 

This transformation involves recognizing that the decay rate can be expressed using the natural exponential base \( e \), facilitating deeper analysis and understanding within mathematical contexts.
