Lesson 2.1: Quadratic Functions Expressed in Vertex Form

Glossary Checklist FAQ

Designers of satellite dishes make use of quadratic functions to create shapes that maximize reliability and efficiency. Many other professions also use quadratic functions to optimize performance, including military tactical units and aerospace engineers. Lesson 2.1 starts with a review of Math 10C linear functions, and progresses into investigating quadratic functions written in vertex form.

In Lesson 2.1, you will

• analyze the characteristics of quadratic functions in vertex form, specifically:

• vertex
  
• domain and range
• direction of opening
  
• equation of the axis of symmetry
• \(x\)- and \(y\)-intercepts.
