### Week 25

Algebra II has started to delve into the vast topic of polynomials and have been reviewing the basic skills associated with them (operations, substitution, and classification). We will start to move into more unchartered waters as we look at their behavior graphically as well as continue to emphasize and develop the skill of factoring. It is crucial during our investigation of polynomials that students become increasingly comfortable with their graphing calculators and its capabilities. Please find the guided notes we started last week below as well as the portions we have already completed below. Reference sheets and homework are also found below--become comfortable with those reference sheets and how you can use them to help you navigate this topic.

Precalculus is heading into Trigonometry! We will start with trigonometry as you have already engaged it in Geometry and begin to extend into the arena of functions and periodic behavior. It will be a long road that will extend across the entire third quarter so it is important to get the foundational concepts early so that as the develop and become more complex you will find it much easier!
