The document discusses graphs of quadratic functions. It begins by reviewing that the graph of a quadratic function y=ax^2+bx+c is a parabola. It explains that the parabola opens up when a>0 and opens down when a<0. It then provides steps for graphing a quadratic function, which include determining the vertex coordinates using the formula x=-b/2a, sketching the axis of symmetry, and finding any intersections with the x-axis or y-axis. Examples of graphing specific quadratic functions are shown. The document concludes by providing exercises for students to practice graphing quadratic functions.
