Abstract
This chapter discusses quadratic equations and quadratic functions, which are the simplest type of non-linear relationship. It illustrates that a quadratic function, when graphed, produces a characteristically U-shaped curve. The chapter then shows how to solve quadratic equations, including simultaneous quadratic equations. At the end of the chapter two applications of quadratic functions in economics are briefly presented.
