an inverse function to f(x) does the opposite task f(x) perfroms
what will be that here @jerr1996

i'm confused :/ would the inverse function be\[ ^5 \sqrt{x}\]
??

\[ F(x)=x^{2} + 5, x \ge0;
G(x)=\sqrt{x-5}\]
is that the inverse?

Yes, if you are confused try to sheck the identity: \(f(f^{-1}(x))=x\).
For example: \(f(x)=x^5, f^{-1}(x)=\sqrt[5]{x},f(f^{-1}(x))=(\sqrt[5]{x})^5=x\).
