Best ResponseYou've already chosen the best response.0C is correct. Since you are raising a fraction between 0 and 1 to a power, the higher the power, the smaller the number will be. For example: For x = 1, 2, 3 (1/2)^1 = 1/2 (1/2)^2 = 1/4 (1/2)^3 = 1/8 As you can see, as x increased, from 1 to 2 to 3, f(x) decreased from 1/2 to 1/4 to 1/8
