**Steve**, Wednesday, November 28, 2012 at 3:02pmfor y=ax^2+bx+c, vertex is at x = -b/2a

if you complete the square, and have

(y-k) = a(x-h)^2 then

the vertex is at (h,k)

the axis of symmetry goes through the vertex.

the sign of the x^2 term determines whether the vertex is a min or max.

So, what do you come up with?
