The cut-off point with the ordinate axis , there is only one, is the one with the first coordinate x = 0 and the second coordinate y = a The cut points of the parabola with the axis of the abscissa , if any, are those that have the second coordinate y = 0 and the first coordinates are the solutions of the quadratic equation a (x – x 0 ) 2 + y 0 = 0 (obtained by requiring the condition y = 0 ). The equation of a parabola is y – y 0 = a (x – x 0 ) 2 . This equation is the parabola with vertical axis and whose vertex is (x 0, y 0 ) .
