Hi,(adsbygoogle = window.adsbygoogle || []).push({});

given two functionsfandg, is there any known condition under which the following is valid:

[tex](f \circ g^{-1}) = (f^{-1} \circ g)[/tex]

Basically I have to find out the requirements for [tex]f[/tex] and [tex]g[/tex] for which composition is commutative in respect to inversion.
