Ginny is studying a population of frogs. She determines that the population is decreasing at an average rate of 3% per year. When she began her study, the frog population was estimated at 1,200. Which function represents the frog population after x years?

f(x) = 1,200(1.03)x
f(x) = 1,200(0.03)x
f(x) = 1,200(0.97)x
f(x) = 1,200(0.97x)

f(x) = 1,200(0.97)^x

Explanation: A 3% annual decrease gives a decay factor of 1 − 0.03 = 0.97, so the population after x years is 1200·(0.97)^x.
