Module 1 - Describing Functions Introduction | Lesson 1 | Lesson 2 | Lesson 3 | 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-83 and TI-83 Plus provides platforms to investigate functions in these three different ways. Lesson Index: 1.1 - Describing Functions Symbolically 1.2 - Describing Functions Graphically 1.3 - Describing Functions Numerically After completing this module, you should be able to do the following: Define and evaluate a function on the TI-83 Plus or TI-83 Use the method of "Guess and Check" to find a root (or zero) of a function Display a function graphically Use the table feature to describe a function numerically Find roots (or zeros) symbolically, graphically and numerically Next> ©Copyright 2007 All rights reserved. | Trademarks | Privacy Policy | Link Policy
