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.
The graph of a quadratic function is called a parabola. A parabola contains a point called a vertex. The parabola can open up or down. If the parabola opens up, the vertex is the lowest point. This point is called the minimum point. If the parabola opens down, the vertex is the highest point.
