According to the definition for composite function,
[tex]g\circ f(x)=g\lbrack f(x)\rbrack[/tex]Substitute the values,
[tex]\begin{gathered} g\circ f(1)=g\lbrack f(1)\rbrack \\ g\circ f(1)=g\lbrack3(1)-1\rbrack \\ g\circ f(1)=g\lbrack2\rbrack \\ g\circ f(1)=(2)-1 \\ g\circ f(1)=1 \end{gathered}[/tex]Thus, the value of the given composite function is 1.
