Communication by Maddie: 1. Direction of Opening: Down Line of Symmetry: X = 0.1 Domain: D(XER) Range: R(-1.3__<__ y__<__ 1.5) Vertex: (0.1,3.4) 2. This image is the character from the simpsons Homer Simpson. This character is funny, but very unintelligent. This image is one of his expressions in the show. I think my parabola was close to the one I calculated. I think I could have chnaged my points around so that both of the lines would match better. I estimated the vertex by looking at the top of Homer Simpson's hair. I also estimated the two other points. I think I should have choosen two other points and maybe the two parabolas would look similar.

Communication of the Slinky, Courtney Edwards

Direction of Opening: Down LIne of Symmetry: 3.5 Domain: D{XER} Range: R{-1<Y, YER} Vertex: 3.5, 0.25 This picture shows a slinky, which is a really exctiting shape because depending on how much you stretch the slinky, the parabola can change. The stretch is very much like the stretch in mant, because it does the same thing. Most objects cannot change their parabola equation like a slinky, which is why this one is so intriuging. I think my parabola is vey close to the exact one, although I had to estimate a lot of points, resulting in the differnce. I think if I had tried a couple of different points I would have been closer, so I'll know do try more than one set of points next time. What I like about this assignnment was that I saw that parabolas are everywhere.
