What exactly does inverse mean? I've seen it mean the "undoing" function, and also simply meaning "1 over" a function.(adsbygoogle = window.adsbygoogle || []).push({});

Consider the function [tex]f(x)=4x + 6[/tex]

Is the "inverse" [tex]f^{-1}(x)=\frac{x-6}{4}[/tex]

or is it [tex]f^{-1}(x)=\frac{1}{4x+6}[/tex]?

I'm getting kinda confused. It doesn't help that inverse trig functions are annotated with a [tex]^{-1}[/tex], when those are actually the 'undoing' functions.
