Quiz on Tuesday, 5 November and will cover two questions from Section 2.6.
Today, we covered a few additional problems from Section 2.6 both algebraically and graphically. Also, we started 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 2.6*: # 7, 8, 11-27 odd**, 47, 51, 55, 59, 63, 67, 71, 73***, 75***, 77***
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.
* All solutions must be in interval notation.
** You do not need to graph solutions.
*** See Section 1.3 for refresher.
