Well, I think your values look better for (f') but mine for f'(x).
Compare the two attached files. I have browsed my ~270 pages math
document, but so far I only see either primes alone or primes with (
after, and both look OK to me.

I don't know how reverse primes are supposed to look or to be used, so
there I am of no help.
