Working With Quadratics: Matching Game

This activity is to help students understand the transformations a quadratic goes under when a coefficient is changed. The objective is to match your quadratic to the given random quadratic with the sliders.
How does the coefficient a effect a quadratic? How does the coefficient b effect a quadratic? How does the coefficient c effect a quadratic? What is the difference in positives and negatives in relation to the coefficient a? What happens when a is a negative number?
