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.
For example, a quadratic function in three variables x, y, and z contains exclusively terms x 2, y 2, z 2, xy, xz, yz, x, y, z, and a constant: with at least one of the coefficients a, b, c, d, e, or f of the second-degree terms being non-zero.
