    Do you mean \(\Large f(x)=x^3\sqrt{x-4}\)?

    Ranado, you kept asking me if I had a boyfriend, when I already gave you my answer. You were annoying me.

    Do you mean \(\Large f(x)=\sqrt[3]{x-4}\)?

    I would not use y, and my first step would be the following: \[\Large f(x)=\sqrt[3]{x-4}\]\[\Large x=\sqrt[3]{f^{-1}(x)-4}\]

    do you know what \(\Large\sqrt[3]{}\) means?
