The video tutorial explains how to find the vertex, axis of symmetry, y-intercept, domain, and range of a quadratic function. It begins with an introduction to the vertex formula and demonstrates how to calculate the vertex using specific values. The tutorial then covers graphing the quadratic function, identifying the axis of symmetry, and finding the y-intercept. It concludes with a discussion on the domain and range of the function, emphasizing the importance of graphing to determine these properties.
