How do I find the rule for f^-1(x) and f^-1(125)? I'm very confused and I would like to know how to do it.

OpenStudy (anonymous):

last time I checked, the word "rule," when used as a verb, means to control. I doubt that one can do this with mathematical expresions.

I'm sorry I meant find the rule. I just don't know what to do because that's all the information they gave me.
