Quiz on Tuesday, 5 November and will cover finding vertex of a quadratic.
Today, we covered most of Sections 3.1 and 3.2. In these sections, we discussed the steps needed to sketch polynomial functions by hand:
- find x-intercepts (see Sections 2.4 and 2.5 for refresher)
- find y-intercept (see Section 1.4 for refresher)
- identify long-term behavior (i.e., Leading Coefficient Test)
- build table to identify additional points (see Section 1.4 for refresher)
- (for quadratic functions only) find vertex
We will use these steps on Thursday to sketch graphs of a few polynomial functions. You should bring in graph paper to class (see http://www.printfreegraphpaper.com/).
The next homework assignment is due on Tuesday, 10 November 2009 and consists of:
Section 3.1: # 1–6, 7–19 odd, 21, 23, 25, 27, 29–34, 45, 47
Section 3.2: # 1–9, 15–47 odd, 59–63 odd, 69–77 odd, 83–89 odd, 99– 107
NOTE: all graphs must be on graph paper.
