Using the definition of composite function:


(f_{\text{ }}o_{\text{ }}g)(x)=f(g(x))

so:


\begin{gathered} f(g(1)) \\ g(1)=3 \\ so \\ f(g(1))=f(3)=2 \end{gathered}

----------------------------------------------


\begin{gathered} g(f(0)) \\ f(0)=4 \\ g(f(0))=g(4)=5 \end{gathered}

----------------------------------------------


\begin{gathered} f(f(4)) \\ f(4)=0 \\ f(f(4))=f(0)=4 \end{gathered}

----------------------------------------------


\begin{gathered} g(g(0)) \\ g(0)=2 \\ g(g(0))=g(2)=0 \end{gathered}
