Explorat ory Challenge Your group will need: Quadratic Matching Game Cards 3. With your group, match four different aspects of a given quadratic function. There are cards for the vertex, equation in standard form, y-intercept and graph. Record your matches in the table below. Your graph should be a rough sketch, but put in at least 3 key points.
