Quadratics 101

A slow glide and fall with the parabola. Kisses the x-axis once, sometimes twice, sometimes not at all. No grading/marking, and do not use Desmos, or you will miss the point of it (FUN). Self-paced, 4–6 hours a week/4weeks. Answers may be singular, multiple, or existentially absent. Indulgence required; calculators will feel neglected. Buckle up.
