Welcome to the main web page for Chapter ONE of PRECALCULUS: College Algebra and Trigonometry. Use this page to move to the desired pointers within the chapter.

The chapter is divided into the following sections:
1.0  Review of Algebraic Expressions
1.1  Real and Complex Numbers
1.2  Inequalities and Absolute Value
1.3  Relations and Functions
1.4  Algebra and Composition of Functions
1.5  Increasing, Decreasing, Symmetry and Inverse Functions

In the textbook there are icons directing you to various support pages. The icon is used to reference pages that demonstrate aspects of using the TI graphing calculators. The icon is used to reference extra material on a topic. And the icon is used to reference further explanations of some point in the text. Below each icon in the text there is a sequenced name for the specific web page being referenced. Those icons and sequenced names are listed below as hyperlinks to the desired pages.
