You're posting in the TI-83 series section of the site, but your syntax looks like TI-89/92+/V200 code. Which is it?

The best way to do it would be to store it as a string, which is the natural data type with Request. Then to evaluate it at x=4, do expr(f)|x=4. This will even work if x is defined to have a value.
