If $b$ is between $0$ up to but not including $1$, the function represents exponential decay. If $b$ is greater than $1$, the function represents exponential growth.
$y = a(b)^x$ $a$ = y-intercept $b$ = Rate of growth/decay If $b$ is between $0$ up to but not including $1$, the function represents exponential decay. If $b$ is greater than $1$, the function represents exponential growth.
