What is so bad about
f x = g x'' where x'' = x' + transform x' = x * scale
(if you really hate inventing temporary names, that is). There's nothing at all wrong with this, assuming it's what you meant to type :-), and it might even correspond perfectly to the mathematical notation used in some textbook. But I would argue that

OMG! "Mathematical" and "subjective" in the same sentence! ;-) Personally, I find that if I've got more than 2 of the thing, I number them rather than attach multiple primes... but that's just me.
