1) Graphing quadratic equations in vertex form involves identifying the vertex (a, h) and the axis of symmetry (x = h) from the equation. 2) The document provides examples of quadratic equations in vertex form and describes the transformations between the graphs and the standard form equations. 3) Key aspects like the vertex, axis of symmetry, direction of opening, and roots are identified and the transformations including stretches, shifts, reflections and compressions are described.
