**Henry**, Wednesday, September 1, 2010 at 8:10pmF(x) = y = -3(x + 3)^2 + k.

Vertex Form:

y = a(x - h)^2 + k.

V(h , k) = V(-3 , 0),

Line of sym = h = -3 = Xv.

h is positive in your Eq because you are subtracting a negative 3.

If you gave me the complete Eq, k = 0.

The graph opens downward since a is negative(-3).
