(1) The document discusses cubic and quartic polynomial functions. Cubic polynomials are of degree 3, while quartic polynomials are of degree 4. (2) The graph of a cubic function is a continuous smooth curve that can have up to two turning points, where the curve changes from increasing to decreasing. These turning points can be local maxima or minima. (3) An example cubic function is graphed and its local minimum and maximum are calculated using a graphing calculator. Quartic functions are similarly discussed and an example graph is shown.
