How to determine if a point is on the graph of a quadratic using vertex form

The video tutorial explains how to verify if a given point lies on a graph by substituting the point's coordinates into an equation and simplifying it using algebraic methods. The process involves substituting X and Y values, applying the order of operations, and verifying the equation's truth to confirm the point's position on the graph.
