Information The vertex form is a special form of a quadratic function. From the vertex form, it is easily visible where the maximum or minimum point (the vertex) of the parabola is: The number in brackets gives (trouble spot: up to the sign!) the x-coordinate of the vertex, the number at the end of the form gives the y-coordinate. It is also called an 'Equation of Degree 2'. The general form is ax 2 + bx + c = 0, where a, b, and c are numbers, 'x' represents the unknown value and a ≠ 0, if a equals zero then its a linear equation.
