Unit 3, Polynomial Functions: Day 2 (BI Chapter 4, Section 1)

Focus: Introduction to Polynomial Functions: End Behavior and Intervals of Increasing/Decreasing

Action Items:

1. Warm Ups

2. Show me HW 3.1 on Monday!

3. Notes on Polynomials, continued

4. HW 3.2: BI p. 162-4 #17-23; 33-36; 51-56. (As always, you should write the problems (WTP) and show your work (SYS) in your composition book).

Notes: Goals for today (continued from yesterday)!

have a sense of the goals of the unit
know the definition of a polynomial, including the standard form
be able to classify by degree and type
identify the leading coefficient
identify end behavior (Desmos Activity: Polynomial Graphing, End Behavior, Vocabulary, and Descriptions)
identify extrema, intervals of increasing and decreasing
Know: ALL POLYNOMIAL FUNCTIONS HAVE THE DOMAIN ALL REAL NUMBERS!

By now, you should be comfortable with linear and quadratic functions. These functions are both types of polynomial functions. In Algebra 2, we expand our understanding to include functions raised to positive integer powers (not just 1 and 2); these are called polynomial functions.

Again, if you are absent, try looking at the powerpoint: Alg 2A Introduction to Polynomials.pptx If you are absent, you should get notes from a friend, or take notes on the powerpoint. If you have further questions, be sure to ask me!
