Exponential Decay when \(\displaystyle{y}={A}{\left({B}\right)}^{{x}}\) when B is between 0 to 1.

Exponential growth \(\displaystyle{y}={A}{\left({B}\right)}^{{x}}\) when B is greater than 1.

Since \(\displaystyle\frac{{5}}{{4}}\) is greater than 1 it is exponential growth.

Exponential growth \(\displaystyle{y}={A}{\left({B}\right)}^{{x}}\) when B is greater than 1.

Since \(\displaystyle\frac{{5}}{{4}}\) is greater than 1 it is exponential growth.
