Set 5: Exponential Functions

Choice B is correct. Choice B is the correct answer. Subtract rate from 1. 1. Identify Rate: $r = 1.2\% = 0.012$. 2. Calculate Factor: $b = 1 - 0.012 = 0.988$. Strategic Tip: $1.000- 0.012 = 0.988$. Choice A is incorrect because it subtracts 0.12 (12%). Choice C is incorrect because it represents growth.
