Question

determine if the equation $y = 15(1.35)^t$ represents exponential growth or decay and justify. hint: think about the growth and decay equations.
growth, because the scale factor is greater than 1
growth, because the scale factor is less than 1
decay, because the scale factor is less than 1
decay, because the scale factor is greater than 1

Explanation:

The general form of an exponential function is $y = a(b)^t$, where $b$ is the base (scale factor). If $b > 1$, it represents exponential growth; if $0 < b < 1$, it represents exponential decay. Here, the base is 1.35, which is greater than 1, so it is growth.

Answer:

A. Growth, because the scale factor is greater than 1
