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. choose the function that represents the frog population after x years. a. f(x) = 1,200(1.03)x b. f(x) = 1,200(0.03)x c. f(x) = 1,200(0.97)x d. f(x) = 1,200(0.97)x
