Cindy made apple pie every weekend. The more apple pies she made, the more practice she gained. The time she took to make the same amount of apple pie every week decreased with practice. The function below shows the number of hours f(x) Cindy took to make an apple pie after she had made it x times: f(x) = 3(0.4)x Which graph best represents the function? graph of function f of x equals 0.4 multiplied by 3 to the power of x graph of function f of x equals 3 multiplied by 0.4 to the power of x graph of function f of x equals 0.4 to the power of x graph of function f of x equals 3 to the power of x
