Honors Pre-Calculus NOTES – Graphing Polynomial Functions . End Behavior . The end behavior of a polynomial function (how the graph begins and ends) depends on the leading coefficient and the degree of the polynomial. • If the degree of the polynomial is odd, the end behavior of the function will be the same as a line. END BEHAVIOR – be the polynomial. Odd--then the left side and the right side are different Even--then the left side and the right are the same. The Highest DEGREE is either even or odd. Negative--the right side of the graph will go down The Leading COEFFICIENT is either positive or negative Positive--the right side of the graph will go up. The end behaviorof a function’s graph is the behavior of the graph as xapproaches positive infi nity (+∞) or negative infi nity (−∞). For the graph of a polynomial function, the end behavior is determined by the function’s degree and the sign of its leading coeffi cient.
