How do you graph a quadratic function efficiently? Explore graphing quadratic functions by writing in intercept form with a lesson that makes a strong connection to the symmetry of the graph and its key features before individuals write equations from graphs using intercepts. Finally, pupils model launched objects by graphing and analyzing quadratics.
