  1. vertex(6,-5)
    Direction is opening down(maximum)
    I don't know the axis of symmetry...but I hope this helped:)

  2. Vertex at x = 6, y = -5. That is the largest possible value of y along the curve.
    Axis of symmetry is x = 6 vertical line.
    Direction of the parabola's opening is down

  3. Oh wait for the axis of symmetry put the vertex form to standard form and then do
    -b/2a

    For example:
    x^2+6x+13 A=1 B=6 C=13
    Axis of Symmetry equation x=-b/2a
    x=-6/2(1)
    x=-3

  4. Sarah,
    (x-6)^2 is the same both sides of x = 6. For this problem you do not need
    [-b +/- sqrt(b^2-4ac) / 2a
