Videos and lessons with examples and solutions to help High School students learn how to graph functions expressed symbolically and show key features of the graph, by hand in simple cases and using technology for more complicated cases.

Graph polynomial functions, identifying zeros when suitable factorizations are available, and showing end behavior.

Common Core: HSF-IF.C.7

Turning Points and X Intercepts of a Polynomial Function

This video introduces how to determine the maximum number of x-intercepts and turns of a polynomial function from the degree of the polynomial function. Examples are shown with graphs.

Real Zeros, Factors, and Graphs of Polynomial Functions

This video explains the connection between zero, factors, and graphs of polynomial functions.
