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)
