This is how it could look like. I know I can make it with pure text, but it would be nice to have something that fits into the awesome icon set.

+1, ideally, the style would be close to the one of the computer modern font of LaTeX

I'd rather a "fx" icon instead of a "f(x)" one in order to simplify. But it would be okay too!

well it's simple to achieve it with pure HTML:
<i>f<sub>(x)</sub></i>
_f(x)_
gilhanan - If the goal is just to have a single instance somewhere, that does work fine, of course. However, if you have a bit of code to generate a series of buttons or something like that, it's nice to be able to assume that the icons are font awesome. The fewer times i have to put in a special case, the better.
In my case, i ended up just making a custom font with some of the icons i wanted, and then i have a CSS file that makes allowances for some of the icons coming from another font. That way, i can still have my code process a fa-bolt the same was as a fa-my-custom-icon or whatever, and the CSS takes care of getting the right font.

How many +1 do we need to get this in? :)
Do I need to organize a campaign here?
If you add up all the +1's and the :+1: 's, this has 60 votes - which should put it on the first page of the icon leaderboard :disappointed:
Here's a completed faFunction icon that I made that works with Font-Awesome v5, intended for use with the regular style:
