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?​

So I can't give you an exact answer,  but here are a couple examples of parabolas and some examples of things they share. (Also a parabola is basically just something with an arch, if you want more info I'd suggest looking at the images tab first to get a visual.)

-A banana

-The McDonalds logo

-A rollercoaster

-Suspension bridges

Are all examples of parabolas. They all share an arch shape, and are either fully or partially symmetrical.

Hope this helps!
