How do I find the equation of the axis of symmetry of a parabola that contains the points (-2,6), (0,-6), (6,6)

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?
