What is an axis of symmetry

The video tutorial explains the concept of the axis of symmetry in quadratic equations, focusing on parabolas. It describes how the axis of symmetry is a line that divides the parabola into two symmetrical halves. The tutorial provides a formula to find the axis of symmetry without graphing, which is the opposite of B divided by 2A. It also includes a non-example to illustrate what does not constitute symmetry.
