More thinking about functions

For this week (9/26 to 9/30) we look more deeply into the functions we have been studying.

Day 1:  Go over the more abstract homework of last week
       HW Extra Practice with Function Operations
Day 2:  Discuss strategies for solving problems
       HW Extra Special Function Practice
Day 3:  "How Do You Know?" Worksheet

Thursday, September 29th is Rosh Hashanah so there is no school. I will also be out on Friday, September 30th.

On Monday, October 3rd we will review and on Tuesday, October 4th we will have a test of the material in Ch 2.

A web site for reviewing...

I would like to recommend a web site were you can watch video lessons whenever your miss class or just want to see the presentation again. It is called brightstorm.com. Here are some for the material we have been covering recently:

• Piecewise Functions
• Composition of functions
• Definition of an Inverse

A week spent looking at functions a different way

This week (9/19 - 9/23) we will be looking at special functions and inverse relations.

Day 1 Special Functions (2.6)
       HW p.129-131/17-25 odd, 26,27,53,55,65,66,73
Day 2 Inverses (2.5)
       HW Finish worksheet of inverses three ways
Day 3 More with Inverses (2.5)
       HW p.122-123/12-48 by 3's,50-52,62 and p.132/90
Day 4 Putting together all the function ideas so far
       HW Finish worksheet of more challenging/conceptual problems

A reminder: short quizzes can happen any time. They are an excellent way for me to check if you are doing and understanding your homework. They also help you know if you can do the problems and do them under pressure. If you do not do well on a quiz, you can get help and then retake the quiz. My goal is for you to understand all of the material, not to have you memorize procedures. Please ask whenever you need help.

We start using the book...

This week (9/12 - 9/16) we will be moving into the book. We will be covering the topics of the book and using it for homework but the questions posed in class will usually be more thought provoking than the presentation given in the book.

Day 1 Absolute Value by hand and with the calculator (1.7, 1.8)
       HW p.58-59/36-72 by 3's
Day 2 Intro to Functions (2.3)
       HW p.108-110/29-38, 47-67 odd, 82, 83
Day 3 Function Operations (2.4)
       HW p.115-116/11-56 by 3's, 59-62
Day 4 More practice with function descriptions and operations
       HW Finish handout of problems

You will also need to explore your calculator using this link. I will be collecting the final certificate of completion on Tuesday, September 20th.

Let's Get Started!

We started the year with two days of Math Challenge problems to get the math part of your brain moving again. This week we will do an Algebra 1 review sheet, a worksheet of literal equation solving (meaning the answers have letters in them) and the Pre-Test to see what you remember from Algebra 1. Remember that you can go to the math caching website for more Algebra 1 practice. (You don't need an answer sheet but here is the link if you want it.) Next week we will start using the book and you will need to have your calculator.
