    -b/2a gives you the axis of symmetry

    well, not an x or y axis persay.... but the center of the thing :)

    if it aint centerd, it aint got no axial symmetry

    its centerd at -4.... so I would take a gander and say no axis of symmetry

    The axis of symmetry is x=-4, by x=-b/2a. I don't see why you would say it has no axis of symmetry..

    It has a vertex, but it is not symmetrical to the x or y axis.... its a big "U" graph that is off centerd.

    It is symmetrical about the line x=-4. It doesn't have to be centered to the x or y-axis to be symmetrical.

    axis of symmetry MEANS does it spin about the y or x axis; just definitional stuff....

    No. The axis of symmetry is any line about which the parabola is symmetrical. http://www.mathwords.com/a/axis_symmetry.htm

    you could be right; but what am I thinking of then?
