How are you specifying the contents of the running head?

Have you tried using   \MakeLowercase{$f(x)$}
or  $\MakeLowercase{f(x)}$  ?

If that doesn't work, then you can try setting the math
in a box and then using that box in the running head;

e.g. (in preamble)

Then at the appropriate place use

    \markboth{.....\copy\mathheadbox ...}{....}

or whatever package commands you might be using
to specify the header.

Actually, you probably don't even need the box.
Just using a macro may be enough:


    \markboth{..... $\effofex$ ...}{....}

Well, it used to be that people would say to never use math in titles.
It became "not done" because of the kind of problem that you are
currently encountering. Another such problem was that the math would
not resize correctly for a title --- but that sizing issue was fixed
as LaTeX got better (e.g., with LaTeX-2e).

This is not to say that you couldn't always do it anyway, if you
worked hard enough, just that it was not easy to get it right.
So publishers (even the AMS) would advise against it, and you
may find that some still do so.

But in TeX you really can do pretty much anything, using macros.
