Introduction

Previously in this unit the graphs of power functions were presented. Radical equation graphs fall under the heading of power functions when the power is between the values of 0 and 1, in other words a fraction. Remember that rational exponents can be translated to roots. Therefore, the graph of Graphing_1is the same graph as Graphing 2. Similarly the graph of Graphing_3 is the same graph as Graphing_4.

Guided Practice

To solidify your understanding of graphing radical functions, visit the following link to Holt, Rinehart and Winston Homework Help Online. It provides examples, video tutorials and interactive practice with answers available. The Practice and Problem Solving section has two parts. The first part offers practice with a complete video explanation for the type of problem with just a click of the video icon. The second part offers practice with the solution for each problem only a click of the light bulb away.
