Module 1 - Describing Functions Introduction | Lesson 1 | Lesson 2 | Lesson 3 | Lesson 4 | Self-Test Introduction Have you heard of the Rule of Three? This rule says that functions should be described three ways: symbolically, graphically and numerically. As you investigate functions from each of these three perspectives and see how the three representations are connected, you will gain a deeper understanding of the important mathematical concept of function. The TI-89 provides a platform to investigate functions in these three different ways. Lesson Index: 1.1 - Basic Features 1.2 - Describing Functions Symbolically 1.3 - Describing Functions Graphically 1.4 - Describing Functions Numerically After completing this module, you should be able to do the following: Reset the TI-89 to its factory default settings Adjust the calculator contrast Define and use a function on the TI-89 Enter and edit commands on the Home Screen Display a function graphically Use the table feature of the TI-89 to describe a function numerically Find roots symbolically, graphically and numerically Next > ©Copyright 2007 All rights reserved. | Trademarks | Privacy Policy | Link Policy
