Problem that confuses students with their approach

The video tutorial explains the confusion students face with parabola problems when the vertex is not given. It emphasizes the importance of plotting the focus and directrix to understand their relationship. The concept of 'P', the distance from the vertex to the focus or directrix, is explained. The tutorial guides students on finding the vertex by calculating the midpoint between the focus and directrix. Finally, it demonstrates how to write the equation of a vertical parabola using the vertex and the value of P.
