1. The problem statement, all variables and given/known data I worked on this question and I made it so far, and now I am stuck on how to finish it. Here is the problem and below I will explain what I attempted. 2. Relevant equations 3. The attempt at a solution I know looking at the last part about using previous homework, I want to prove that the function is contractive. If I can prove that, I can use a previous assignment which says contractive functions have a fixed point. Here is what I have in my proof so far. I am stuck now and not completely sure where to go next. Any advice is appreciated.
