Sketching the Graph of Higher Degree Polynomial Functions

This video tutorial teaches how to sketch graphs of higher degree polynomials by finding zeros and determining end behavior. It covers the steps to find x-intercepts, explains the end behavior based on the degree and leading coefficient, and discusses sign changes at roots. The tutorial includes examples to illustrate these concepts, emphasizing the importance of understanding multiplicity and intervals for accurate graphing.
