Graph a horizontal parabola when the distance to the focus is a fraction

The video tutorial explains how to graph a parabola by transforming its equation into standard form. It covers identifying the vertex, focus, and directrix, and determining the direction of the parabola's opening. The process involves manipulating the equation, calculating key values, and understanding the relationship between the vertex, focus, and directrix.
