# Ch 11: Rational and Radical Functions

Use our video lessons and quizzes to help you understand the characteristics of rational and radical functions. Learn how to graph these functions and find their domain and range.

## Rational and Radical Functions - Chapter Summary

Sorting out the differences between radical and rational functions could be easier than you think. Let our experienced instructors show you what a rational function is and provide you with strategies for finding its domain and range. They can also help you tell the differences between the vertical, horizontal and slant asymptotes found in their graphs and provide you with tips for finding zeros of these functions, determining their end behavior and locating their y-intercepts. The uses of inverse variation and the steps required to graph rational expressions are covered as well.

The second half of this chapter helps you perform some of the same tasks, but with radical functions. In addition to learning how to find their domain and range, you can practice graphing radical functions and solving radical equations. Lessons also show you how to graph square and cube root functions. Use this chapter to examine the following:

• Vertical asymptotes
• Horizontal asymptotes
• Slant asymptotes
• End behavior
• Y-intercepts
• Inverse variation

Our chapter on rational and radical functions features entertaining video lessons lasting between five and ten minutes each. You can view them in any order and as many times as you like. The same thing goes for the matching transcripts, which are supplemented with links to text lessons that define key mathematics terminology. If you'd like to check your understanding of the material, each lesson also includes a self-assessment quiz that links back to video content.
