Answer explanation

Exponential growth is when (b) is greater than 1. So our number inside the parenthesis needs to be greater than 1. So we must choose a number greater than 12 so when we divide it becomes bigger than 1. 36 is the only number bigger. 36/12 = 3 and 3 > 1, so its exponential growth.
