Graphing a horizontal parabola by putting it in vertex form by completing the square

The video tutorial covers the process of analyzing a parabola with a horizontal orientation. It begins with an introduction to the differences in the formula compared to previous problems. The instructor then explains how to complete the square to convert the equation into vertex form. The tutorial continues with finding the vertex and axis of symmetry, followed by calculating the focus and directrix. Finally, the video demonstrates how to determine the latus rectum and sketch the graph of the parabola.
