    Do you mean\[y=2(x-4)^{2}+7\]

    So you know that vertex form is \[y=a(x-h)^{2}+k\] and that (h,k) is the same as (x,y) right?

    Well the axis of symmetry is just x. And since x is 4 in this, the equation of the axis of symmetry is x=4

    Kinda. The part I don't get is the (x-h)^2 part. I forgot the rule for squaring things inside of parentheses ._.
