BOB Unit: Rational Functions

I enjoyed this unit. For some reason I like to solve equations and simplify them. But here is the thing, I don't think this skill will be used in the real world at all. I didn't really like graphing these rational functions though. They weren't hard, they just took a lot of time to do. I am interested in the next unit because I do not know much about the constant "e" and what it does or how it works. It is getting to that point of the trimester where its hard to recall all the units we have done. I am forgetting some of the methods that I have learned earlier. I can't even remember what the first unit was about.I am hoping that the exam is not as exact as the tests we take. If it is, I would like to make sure we take a couple of days to prepare ourselves for the final.
