The video tutorial explains the concept of reflections in the context of quadratics. It begins with a general discussion on reflections over the X and Y axes, using coordinate points and graphs. The tutorial then delves into how reflections apply to quadratic graphs, emphasizing the importance of the 'A' value in determining the direction of the reflection. The video also covers the symmetry of quadratic graphs and how reflections are primarily vertical due to the axis of symmetry.
