Pre-Calculus Chapter 2 Essential Questions

For Chapter two I have devised a summary for my students to complete.  Below are the Essential questions I am asking my students to review and make sure they understand.  I will have them insert their summary to the comment section below.

Directions: For your summary you will choose to answer some of the questions outlined below in a logical format to bring together what you have learned for this Unit.  In is important to answer the questions and connect them in a format that describes in your view what you have taken from this unit.  At the end of the summary you may also bring up additional questions that you still need answered or clarified.  The summary is your interpretation of the material from the unit and should not be based on other student or book answers.

Essential Questions: Answer the following in a summary for what you have learned for the given information.
