The video tutorial explains how to analyze a quadratic function, specifically f(x) = 2x^2 - 11x - 21. It covers finding x and y intercepts, the equation of the axis of symmetry, and the vertex. The tutorial also demonstrates graphing the function and verifying the results using graphing software. Key concepts include factoring to find intercepts, using the quadratic formula for the axis of symmetry, and calculating the vertex.
