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.
A quadratic function is one of the form f(x) = ax2 + bx + c, where a, b, and c are numbers with a not equal to zero. The graph of a quadratic function is a curve called a parabola. Parabolas may open upward or downward and vary in width or steepness, but they all have the same basic U shape.
