First let us answer it as if the input is 12. Then the output is 36. F (12) = 36 If the input is 13, then the output is 39. F (13) = 39 So we know the answer is between 36 and 39 The output of 12.5 is the same as the output of 12 plus the output of. 5 F (12.5) = F (12) + F (.5) = 36 + 1.5 = 37.5 So the question is really what is the output of. 2 F (12.2) = ... The same as Y=3X with X being the input.
