Unit 3, Lesson 3, Investigation 1 - day 2
Students used graphing calculators to find the vertex (max/min) of the quadratic functions on page 209 #2.
Goal - how could we find vertices WITHOUT using the graphing calculator? Look for patterns!
No Homework

Homework Check
Multiply Binomials - 2 methods...
- Juan's Method (using the area model)
- Anna's Method (double distribution)
If you missed today, you need to make sure that you see how these methods work. There are posters up in the room and you should work with me or another student to get these methods down.

Domain & Range - Practice & Discussion
*** Practice on Domain & Range will occur during the first 15 minutes of class from 11/11-11/15. Re-assessment will occur on either 11/16 or 11/17. This worksheet is only the problems - not the answers or solutions. Make sure that you check with fellow classmates or with me for the understanding. Feel free to do the problems and give them to me to check for you - if you're confident that you can do it without discussion/help.
Alejandro's Method: Alejandro multiplies binomials vertically. Get notes from a classmate OR come in for a demonstration
Ellen's Method: AKA: FOIL You can find a demo of the "FOIL" method on MathTV.
Choose (on the left side) Algebra. Under Algebra choose Polynomials. Under Polynomials choose Multiplication with Polynomials. Then choose any instructor for Problem #3 (2x+3)(5x-4).
