Big idea for your notes:
What are the Six Parent Functions in Standard Form? (Use your favorite search engine if the video does not give you all the information you need...) Parent Function Rap

Big idea for the notes: Do you know what a QR Code is and how to use one?

Download "QR Code Reader" for iPad or iPhone by TapMedia LTD for a group classroom activity on Monday, if you have one of these devices. For Android devices, I recommend "Barcode Scanner" from the Google Play store.

Did this work?? If not, I recommend trying a different Barcode Scanner App.

Key Questions: What are the methods for solving systems of equations? How do you determine the number of solutions? Is one method ever better than the other? Why?

Below is a screen cast of the same PowerPoint on Solving Systems, but with voiced over instructions. However, if you've already HAD IT UP TO HERE with my voice, then just hit MUTE!! :) But then I guess that pretty much defeats the purpose of the voiced over instructions, so maybe you just want to click through the PowerPoint above. Either way, enjoy!

Practice

Solving Sytemswith answers. Although the worksheet says elimination you need to be proficient at using both methods. As you practice, consider why it might be better to use the substitution or elimination method. Be prepared to discuss in class.

Big Ideas: What does it mean graphically to be a solution to an inequality? What about to a system of inequalities? How many equations constitute a system?

A calculator company produces a scientific calculator and a graphing calculator. Long-term projections indicate an expected demand of at least100scientific and80graphing calculators each day. Because of limitations on production capacity, no more than200scientific and170graphing calculators can be made daily. To satisfy a shipping contract, a total of at least200calculators much be shipped each day. If each scientific calculator sold results in a$2loss, but each graphing calculator produces a$5profit, how many of each type should be made daily to maximize net profits?
