Videos, worksheets, solutions and activities to help PreCalculus students learn how to graph polynomial functions.
Graphing Polynomials, Sec. 3.2, Part 1 (of two parts)
Here we learn to sketch the curve of a polynomial function without the aid of a graphing calculator. Also, no calculus methods will be used.
Graphing Polynomials, Sec. 3.2, Part 2 of 2
In this video, we graph y = -5x4 − 30x3 − 45x2 and we learn about “bouncing” x intercepts.
Polynomial functions and their graphs
Defines polynomial functions and discusses features of their graphs, such as increasing and decreasing.
