Graphing polynomial functions worksheet teachers pay. Be sure to show all xand yintercepts, along with the proper behavior at each xintercept, as well as the proper end behavior. Roller coaster crew ray and kelsey have summer internships at an engineering firm. Introduction a polynomial function is a function such as a quadratic, a cubic, a quartic, and so on, involving. This pattern has one hexagon surrounded by six more hexagons. Sketch the following polynomials on the axis provided. Here is a set of practice problems to accompany the graphing polynomials section of the polynomial functions chapter of the notes for paul dawkins algebra course at lamar university. Quick questions is an activity that helps students identify and correct common math mistakes. This algebra 2 and precalculus video tutorial explains how to graph polynomial functions by finding x intercepts or finding zeros and plotting it using end behavior and multiplicity. To graph polynomial functions, find the zeros and their multiplicities, determine the end behavior, and ensure that the final graph has at most n 1 turning points. If you look at a cross section of a honeycomb, you see a pattern of hexagons. Using the function p x x x x 2 11 3 f find the x and yintercepts. Polynomial functions and basic graphs guidelines for.

Graphing a polynomial function helps to estimate local and global extremas. You can conclude that the function has at least one real zero between a and b. Polynomial functions graphing multiplicity, end behavior. To graph polynomial functions, find the zeros and their multiplicities, determine the end behavior, and ensure that the final graph has at most \n. Test points test a point between the intercepts to determine whether the graph of the polynomial lies above or below the axis on the intervals determined by the zeros. A polynomial function of degree n has at most n 1 turning points. Chapter 2 polynomial and rational functions 188 university of houston department of mathematics example.
