SP #2: Unit E Concept 7: Graphing Quadratics and Include identifying All Features

In this Student Problem, students were to create their own Quadratic with our four selected zeroes (one with a multiplicity of two and two more each with the multiplicity of one). With the zeroes, we needed to complete the square in order to make the equation "graphable." But before graphing, the end behavior must be identified. For example, my own Quadratic has an End Behavior with both pointing up because it was an Even Positive. To find End Behavior, look at the Leading Coefficient and Exponent. Finally, we graph! All five features (Equation, Factored Equation, End Behavior, X-intercepts- with multiplicities, and Y-intercept.

The trickiest part for this Student Problem was finding four zeroes that would work smoothly together. After that, the entire problem ran generally well.
