This question already has an answer here:

For example, how do I the symbol f(x) and make it appear as mathematical appearing instead of just appear as text.

I know I am going to get downvotes for this, but I couldn't find any help files regarding this. Thanks to anyone who answers!

  • $\begingroup$ f(x) gives f(x). $f(x)$ gives $f(x)$. $$f(x)$$ gives $$f(x).$$ $\endgroup$ – user93957 Feb 2 '14 at 9:04

This mentions the system used. If you want f(x) to look like $f(x)$. Then type \$ f(x) \$.
