9.6-9.7, due on October 26

This section is straightforward. I have a fairly good grasp of the material. The most difficult parts included finding the inverse of the permutation. Just the way that it's phrased in the book is a little confusing. Other than that was just the bogging down amid the proofs about inverse functions, but they're still very easy probably due to the fact that we've talked about inverse functions since high school.

The neatest part for me was example 9.12 and finding the inverse of that function. The solution was very elegant and in a way that I wouldn't have thought to do. Instead that set up the f of f^-1 and plugged f^-1 into f and solved for f^-1. It's so easy but it was different than my thought.
