A3.6

sketch or graph a quadratic relation whose equation is given in the form $y=a{x}^2+bx+c$, using a variety of methods (e.g., sketching $y=x^2-2x-8$ using intercepts and symmetry; sketching $y=3x^2-12x+1$ by completing the square and applying transformations; graphing $h=-4.9t^2+50t+1.5$ using technology);
