Oh. This is a fun one. I'm going to be difficult and rename some things to have them make more sense. Your input variable is now your control variable. Your output variable is now your response variable. In an f(x) = y scenario, x is control and y is response. I call it the control variable because it's the only part of the function that you can actually control. You choose what to input. This also works well for describing domain and range, because a king's domain is the part of the world that he controls. So going back to f(x) = y: x is our control, so our x values are our domain. Similarly, our response variables are our range of possible outputs. In our f(x) example: y is our response variable, so the values of y make up our range. There will be the odd instance like f(z) = k, but this shouldn't bother us because our control variable is z and our response variable is k. Wash, rinse, and repeat for our definitions and our simile to remember what's going on.
