Axis Negative yaxis Thus, we can derive the equations of the parabolas as y 2 = 4ax y 2 = 4ax x 2 = 4ay x 2 = 4ay These four equations are called standard equations of parabolas It isFor horizontal parabolas, the vertex is x = a (y k)2 h, where (h,k) is the vertex The focus of parabolas in this form have a focus located at ( h , k) and a directrix at x = h The axis ofBut the equation for a parabola can also be written in "vertex form" y = a ( x − h) 2 k In this equation, the vertex of the parabola is the point ( h, k) You can see how this relates to the
