##### 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
