Best ResponseYou've already chosen the best response.0So you know that vertex form is \[y=a(xh)^{2}+k\] and that (h,k) is the same as (x,y) right?

Best ResponseYou've already chosen the best response.0Well the axis of symmetry is just x. And since x is 4 in this, the equation of the axis of symmetry is x=4
