Match the one-to-one functions with their inverse functions.
inverse function
f^-1(x)=4(20-x)< >
f^-1(x)=x-7< >
f^-1(x)=8(x+7)< >
f^-1(x)=-3(x-1)< >

function
f(x)=x/8-7
f(x)=x+7
f(x)=1-x/3
f(x)=20-0.25x

The inverse of a function is obtained by making x the subject of the formular of the function.

Given the function

the inverse of the function is obtained as follows:
