The graph of a quadratic relationship is in the shape of a parabola. Parabolas are symmetric arcs and are useful for modeling relationships such as the height of a projectile over time or the curve of the cables on a suspension bridge. Think about where you have seen a parabolic arc in real life. What unique features did it have, and where did you see symmetry in the relationship?
