Best ResponseYou've already chosen the best response.1\[\begin{align} f(x)=\frac{x+1}{x3} & \implies y=\frac{x+1}{x3} \\&\implies x=\frac{y+1}{y3} \\& \implies x(y3)=y+1 \\ &\implies xy3x=y+1 \\ &\implies xyy=3x+1 \\ &\implies y(x1)=3x+1 \\ & \implies y=\frac{3x+1}{x1} \\ & \implies \boxed{ \color{red}{f^{1}(x)=\frac{3x+1}{x1}}} \end{align}\]
