What is the inverse of this function [tex]f(x) = x^3 + 2x[/tex]?(adsbygoogle = window.adsbygoogle || []).push({});

***************************************

[tex]f(x) = x^3 + 2x[/tex]

[tex]y = x^3 + 2x[/tex]

interchange [tex]x \Leftrightarrow y[/tex]

[tex]x = y^3 + 2y[/tex]

and it's a dead end to me ...
