Honestly? Repetition. Using the phrase "f maps 2 to 5", lots of "when the input under f is 2, the output is 5" and the like. Lots of color coding. Function machines to show how to build up functions from simpler functions. No magic wand, though

That’s definitely where I’m at! Also a lot of planned variation in terms of input variable and composed functions to get students conditioned to understanding how it works.
A lot of “f is a rule that we’ve defined and applied to an input ‘x’” also. I wish I had a magic wand!
