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.
So, given a quadratic function, y = ax 2 + bx + c, when a is positive, the parabola opens upward and the vertex is the minimum value. On the other hand, if a is negative, the graph opens downward and the vertex is the maximum value.
