You will notice that the points allow you to identify the vertex and to know if it is a maximum or a minimum. You can also pick any single coordinate pair to find any other values needed for the function's definition equation. Use standard form first, and then multiply later to transform into general form.

---- On careful examination of your given coordinates for x and f(x), a mismatch is happening for your point (-4,5). The point does not agree with the required symmetry for a parabola. This point can NOT be on your expected parabola. The coordinates you list will not make a parabola.
