Functions can be thought of as machines by thinking of inputing a number into a machine with a formula and the machine is processing it and it delivers an answer which is the output. The domain is the numbers that you are allowed to use as the input. The range is the set of different outputs you can get. The inputs I insert in the functions machine to acquire the same outputs are F (1), G(2), H(6) and P(1) which all have the output 1. I could not find numbers that cannot be the output of these functions if you have let me know. What else do you want to know about function machines?

i love your example of the function machine, you explain it better then I did

Nice work. What happens if you plug a negative number into the first machine F(x)?
