Graphing a quadratic function in vertex form with dilation

The video tutorial explains how to use the vertex form to graph the equation y = 3x^2. It covers the importance of vertex form in understanding transformations and dilations. The tutorial demonstrates how to graph the equation by identifying the vertex and axis of symmetry, and how to use these to plot points and complete the parabola. The role of the parameter 'a' in affecting the graph's shape is also discussed.
