Notes Over 3.2 Leading Coefficient and Degree Test If leading coefficient is positive, it ends going up. If leading coefficient is negative, it ends going down If degree is odd, it starts and ends on opposites sides If degree is even, it starts and ends on the same side

Notes Over 3.2 Leading Coefficient and Degree Test If leading coefficient is positive, it ends going up. If leading coefficient is negative, it ends going down If degree is odd, it starts and ends on opposites sides If degree is even, it starts and ends on the same side Determine right-hand and left-hand behavior of each. – Because the leading coefficient is negative – Because the degree is odd (the opposite)– it falls to the right. it falls to the right. it rises to the left. it rises to the left.

Goes straight through Bounces off point Notes Over 3.2 Zeros of a Polynomial Function Let n be the degree of the function. Then (n – 1) is the most turns the graph will have. n is the most number of zeros of the function (x-int). Find all of the zeros of the function, and use it to determine the number of turning points. Three turning points Three turning points
