FYI: Different textbooks have different interpretations of the reference standard form of a quadratic function. Some say f (x) = ax2 + bx + c is standard form, while others say that f (x) = a(x - h)2 + k is standard form.
Completing the Square. A quadratic function in the form y = ax 2 + bx + c is not always simple to graph. We do not know the vertex or the axis of symmetry simply by looking at the equation. To make the function easier to graph, we need to convert it to the form y = a(x-h)2 + k.
