The video tutorial explains how to graph a quadratic equation in the form y = ax^2 + bx + c. It covers finding the axis of symmetry using the formula x = -b/2a, plotting the axis, and creating a table of values to identify the vertex. The tutorial demonstrates reflecting points over the axis of symmetry to complete the graph and discusses finding y-intercepts and estimating x-intercepts.
