Axis of Symmetry in Quadratic Functions

The video tutorial explains how to compare two quadratic functions by finding their axes of symmetry. It introduces the formula H = B / 2a to determine the axis of symmetry, which is the x-value of the vertex of the quadratic function. The tutorial demonstrates solving two quadratic equations using this formula, resulting in axes of symmetry at x = 2 and x = -2.
