In which direction does the parabola open
Web13 sep. 2011 · The focus of a parabola is a fixed point that lies on the axis of the parabola "p" units from the vertex. It can be found by the parabola equations in standard form: (x-h)^2=4p (y-k) or (y-k)^2=4p (x-h) depending on the shape of the parabola. The vertex is defined by (h,k). Solve for p and count that many units from the vertex in the direction ... WebDescribe the key features of the parabola y2 = 8x. P would be equal to 2.
