# How do you determine whether each function represents exponential growth or decay y=3(5/2)^x?

Exponential functions are in the form $y = a {b}^{x}$
If $a$ is positive and $b$ is greater than $1$, then it is exponential growth. If $a$ is positive and $b$ is less than $1$ but greater than $0$, then it is exponential decay.
$\frac{5}{2}$ is greater than $1$
