# Chapter 12: Rational Equations and Functions; Statistics

Difficulty Level:

**Basic**Created by: CK-12

The final chapter of this text introduces the concept of **rational functions,** that is, equations in which the variable appears in the denominator of a fraction. A common rational function in the **inverse variation model,** similar to the direct variation model you studied in chapter 4 lesson 6. We finish the chapter with solving rational equations and using graphical representations to display data.
