The video tutorial covers graphing parabolas, starting with finding the axis of symmetry and calculating points on the graph. It demonstrates how to draw the graph and analyze solutions, including using graphing calculators for more complex equations. The tutorial concludes with a real-world application involving the path of an arrow, modeled by a quadratic equation, to find when it hits the ground.
