Today in class 12/5 we talked about the definition of inverse functions. We also discussed the factors that have to be true for two functions to be inverse. We discussed and did practice problems on how to find and verify/ prove inverse functions. We went over why some functions must have restrictions put on them in order to find the inverse functions. If a function doesn't pass the horizontal line test it must have restrictions on it's domain before the inverse function can be found. There was no homework tonight.

Yesterday 12/4 in class we went over the homework from Monday and went over how to decompose functions. We also made a table about what Opposite, Reciprocal, Additive Inverse, Multiplicative Inverse, and Inverse functions. We also went over what Identity was. Our homework was in the Glencoe Precalculus book assignment 3.
