Graphing a sideways parabola using the focus and directrix

The video tutorial explains how to graph a conic section by first identifying the vertex, which is at the origin (0,0) in this example. The instructor discusses the concepts of focus and directrix, emphasizing the importance of the P value in determining the graph's orientation. The focus is located to the right of the vertex, and the directrix is to the left, with the parabola opening towards the focus. The tutorial highlights the symmetry between the vertex-to-focus and vertex-to-directrix distances.

What does it mean if P is positive in the context of a parabola's orientation?
