Instructional Ideas
  • After developing the equation of a parabola from the definition, compare what is known about quadratic equations and the equation of parabola, both algebraically and graphically
  • Extend the lesson to discuss the changes if the vertex was not at the origin; start with vertical or horizontal shifts before combining the two shifts
Classroom Considerations
  • Only refers to parabolas with a vertex at the origin
  • Provides a visual representation of what constitutes a conic section
  • No answer key provided
