$f^-1(x) =x + 12$

to find the inverse of this function change the subject to express x in terms of y.

ie. x - 12 = y

$rArr x = y + 12$

this allows you to find x when you know y. The inverse function is normally expressed using x.

$rArr f^-1(x) = x + 12$

How do you find the inverse of y=x-12y=x-12?
