How to find the find the focus and directrix from a sideways parabola with fractions

The video tutorial explains how to graph horizontal parabolas by identifying key components such as the vertex, focus, and directrix. It covers the calculation of the P value and its impact on the direction of the parabola. The tutorial emphasizes understanding the relationship between these elements and how they influence the graph's shape and orientation.

What is the relationship between the directrix and the focus of a parabola?

Describe the process of sketching a parabola based on its vertex and focus.
