Answer:

The inverse function is;


f^(-1)(x)=x-4

Step-by-step explanation:

Given a function;


f(x)=x+4

The inverse function;


f^(-1)(x)

Can be derived by making x the subject of formula;


\begin{gathered} f(x)=x+4 \\ x=f(x)-4 \\ f^(-1)(x)=x-4 \end{gathered}

The inverse function is;


f^(-1)(x)=x-4
