How can we determine if a quadratic has a max or min value

The video tutorial covers quadratic functions, focusing on their standard form and graphical representation as parabolas. It explains how to determine the maximum or minimum values of a quadratic function's vertex both graphically and algebraically. The tutorial provides examples to illustrate these concepts, emphasizing the role of the leading coefficient in determining the parabola's direction.
