Best ResponseYou've already chosen the best response.0\(\Large f(x)=\sqrt[3]{ \frac x9}4\) make f(x) = y \(\Large y=\sqrt[3]{ \frac x9}4\) swap x and y terms \(\huge \color{red}x=\sqrt[3]{ \frac {\color{red}y}9}4\) now put x in terms of y \(\Large x=\sqrt[3]{ \frac y9}4\) \(\Large x+4=\sqrt[3]{ \frac y9}\) \(\Large (x+4)^3=\frac y9\) \(\Large 9(x+4)^3=y\) \(\Large 9(x+4)^3=f^{1}(x)\) \(\Large f^{1}(x) = 9(x+4)^3\) does this make sense @PHUNISH ?
