First we looked at the parabolas and worked out the ones we definitely knew; y=x^2 and y=-(x^2). Using the two equations that were given, we worked out the y-intercept as well as the maximum/minimum point of each equation. After doing this, we were able to figure out that y=x^2-12x+27 was parabola L and y=-x^2+12x-36 was K.

This enable us to be able to quickly work out the rest of the graphs; I was the inverse of L and J was the inverse of K. Knowing this enabled us to find out the rest of the graphs by using the y-coordinate of the turning point to help form equations for the rest of the parabolas.
