Assignment for Friday, December 14, 2007

Due Monday, 12/17/07

Two worksheets:

Systems of Equations: Elimination Method #1-7 This is review from last year. Don’t forget to CHECK your solution. We will also review solving systems by graphing at solving by substitution next week. The answer to #1 is (-4, 2).

Graphing Quadratics: #1-5 This is new. Choose points for x, solve for y, then plot the point (x, y). Choose x = -2, -1, 0, 1, and 2. Answer the question at the bottom, too. (’a’ is the coefficient of the x-squared term.)
If we have a snow day on Monday I will try to post answers to the first worksheet here so that we don’t have to take the time to go over that in class on Tuesday.

One more thing:  bring your graphing calculator to classs–we will be using the calculator to study the quadratics.  (You are expected to have your graphing calculator with you to do the Math A Exam, so you will be expected to have yours with you as we prepare for the Exam.)
