\mathrm{A\: function\: g\: is\: the\: inverse\: of\: function\: f\: if\: for}\: y=f\mleft(x\mright),\: \: x=g\mleft(y\mright)\:

To find the inverse of a function:


f(x)=(2)/(x-5)

We will follow the steps below

Step 1: Replace f(x) witth y


y=(2)/(x-5)

Step 2: interchange x with y


x=(2)/(y-5)

Step 3: Make y the subject of the formula


\begin{gathered} y-5=(2)/(x) \\ \\ y=(2)/(x)+5 \end{gathered}

Thus, the inverse of the function is:


y=(2)/(x)+5
