Algebra 86 - Graphing Polynomial Functions - Part 1

Calculators and graphing utilities are available that are capable of creating accurate graphs of polynomial functions. However, it is often desirable to sketch a quick representation of a function's graph to get a general idea of its behavior. But given a particular polynomial function, how can we sketch that functions graph? In this lecture, we examine characteristics common to the graphs of all polynomial functions that are important to know when sketching the graph of a polynomial function.
