# Chapter 10: Quadratic Equations and Functions

Difficulty Level: At Grade Created by: CK-12

As you saw in Chapter 8, algebraic functions not only produce straight lines but curved ones too. A special type of curved function is called a parabola. Perhaps you have seen the shape of a parabola before:

• The shape of the water from a drinking fountain
• The path a football takes when thrown
• The shape of an exploding firework
• The shape of a satellite dish
• The path a diver takes into the water
• The shape of a mirror in a car’s headlamp

Many real life situations model a quadratic equation. This chapter will explore the graph of a quadratic equation and how to solve such equations using various methods.
