(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A function from the real numbers to the real numbers is one to one on an interval I if it is strictly increasing on that interval.

Any help please!!!

2. Relevant equations

3. The attempt at a solution

I am not quite sure how to prove it, I know that the use of strictly increasing is important as far as if x1 < x2, then f(x1) < f(x2). A hint I was told to use is contradiction.
