Weh ave the following:

They ask us to find the functions that make up h (x) knowing that:


\begin{gathered} h(x)=\sqrt[3]{x^2-6} \\ \mleft(f\circ g\mright)\mleft(x\mright)=h(x) \end{gathered}

Therefore:


\begin{gathered} f(x)=\sqrt[3]{x} \\ g(x)=x^2-6 \\ \text{therefore} \\ (f\: \circ\: g)(x)=\sqrt[3]{x^2-6} \end{gathered}

The answer is:


(\sqrt[3]{x},x^2-6)
