If the y is squared, it is horizontal (opens left or right). If a is positive, the parabola opens up or to the right. If it is negative, it opens down or to the left. The …
WebbIn addition, the parabolas can be opened to the right, to the left, up and down. Horizontal parabola that opens to the right This parabola is obtained when the directrix is vertical and the parameter p is positive. Horizontal parabola that opens to the left This parabola is obtained when the directrix is vertical and the parameter p is negative. WebbThe point ( x, y) represents any point on the curve. The distance d from any point ( x, y) to the focus \displaystyle {\left ( {0}, {p}\right)} (0,p) is the same as the distance from ( x, y) to the directrix.
