In this lesson, students write an equation for a parabola and rewrite it in vertex form. Then, they match graphs of parabolas to equations. Students reason abstractly and quantitatively (MP2) as they create a parabola equation by applying the concept of distance calculations.
- Generalize (using words and other representations) the process of repeated distance calculations to derive an equation for a parabola in the coordinate plane.
- Let’s write an equation for a parabola.
The graphing technology is for use in the extension problem of the activity Card Sort: Parabolas.
- I can derive an equation for a parabola in the coordinate plane given a focus and a directrix.
