Rearrange to make the subject, so you will get:
This is your inverse. Remember to change it back to correct format, which is:
I should have tried harder. The question is all too easy.
I always use a simple trick to remember inverse functions, especially with linear equations:
A function's slope times the inverse of that functions slope equals -1
Thanks for Rule of Thumb.
