Chapter 9: Conic Sections and Rational Functions

In this chapter:

  • Use the distance formula to find the distance between two points on a plane and to solve distance and rate problems
  • Learn about conic sections— circles, ellipses, parabolas, and hyperbolas—which are created by intersecting a plane and a cone
  • Investigate the properties of conic sections
  • Write the equations of conic sections in different forms
  • Study rational functions and learn special properties of their graphs
  • Add, subtract, multiply, and divide rational expressions
