Week 32

Algebra 2 finalizes their investigation and construction of the graphs of rational functions. It is absolutely essential to make the connection between the algebraic manipulations and understandings of these functions and their graphs. I will be away from school both Thursday and Friday of next week trying to learn how to better use the SmartBoard (you know I need that). Remember to take advantage of the exercise practice at Please find a rather complicated rational function below. The steps to graphing it can be found here.

Precalculus is going to continue with sine and cosine functions in the attempt at mastering all the different transformations that result in changes in amplitude, vertical shift, phase shift and period. The change in one parameter, amplitude, is captured in the image below:
