AI Drawing Prompt Reference

Draw a parabola, marking its vertex and focus, and represent the direction from the vertex to the focus with a vector. Calculate the distance between the vertex and the focus. Then, draw two more parabolas, marking their vertices and foci, representing the directions from the vertices to the foci with vectors, and calculating the distances between the vertices and foci. Finally, draw the directrices for both parabolas, marking their positions.
