How to find the Axis of Symmetry

The video tutorial explains the concept of the axis of symmetry, particularly in quadratic equations. It begins by defining axis and symmetry, then introduces the equation for the axis of symmetry as x equals negative b over 2a. The tutorial includes an example problem to demonstrate how to apply the equation and plot the axis of symmetry on a graph. The video emphasizes understanding the equation and visualizing the axis as a vertical line on the coordinate plane.
