Graphing Quadratic Equations

Build an understanding of vertex form and its relationship to the graph of a quadratic function. Through graphing, scholars learn the horizontal translations, vertical translations, and reflections results of manipulating a function. Once this is established, they connect the transformations to the vertex form created by completing the square.
