It looks different, but yet the same. Scholars view a video that introduces them to the vertex form for a quadratic equation. Pupils realize that though the equation looks different, its graph is still a parabola, and the key features are all still there. Class members learn a new method to quickly graph a quadratic knowing the vertex and then practice graphing and finding key features using the worksheets.

Concepts
