Parabolas

We did parabolas on chapter 7 of this semester. Through researching on internet, I now can identify "parabolas" as the curve formed from all the points (x, y) that are equidistant from the directrix and the focus. The line perpendicular to the directrix and passing through the focus (that is, the line that splits the parabola up the middle) is called the "axis of symmetry". I found this chapter to be relatively interesting since I personally like the graphing section of math a lot. A parabola equation is (x-h)^2=4c(y-k) for vertical shift. (Y-k)^2=(x-h) applies for horizontal shifts.
