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.
If a < 0 , then k is the maximum value of the function. If a > 0 , then k is the minimum value of the function. Below these ideas are illustrated. Figure %: The graph of the parabola y = a(x - h)2 + k . It is a quadratic function in standard form. On the left a < 0 , and on the right a > 0 .
