    Hello, leki07!

    Did you make a sketch?


    How do I find the equation of the axis of symmetry of a parabola
    that contains the points (-2,6), (0,-6), (6,6)
    Code:
                    |   :
               o    |   :        o
                    |   :
                o   |   :       o
            (-2,6)  |   :     (6,6)
                    |   :
          ----------+---:------------
                  o |   :     o
                    |   :
              (0,-6)*   :   o 
                    |   o

    They made it very easy for us . . .

    We know the axis of symmetry bisects the parabola.
    Since (-2,6) and (6,6) are at the same height,
    . . the axis is halfway between them.

    Got it?
