Algebra 2/Trigonometry Name: __________________________6.6 Worksheet Date: ________________ Block: _____

For each polynomial, complete the following: (a) Use the Leading Coefficient Test to describe the end behavior. (b) Use your graphing calculator to locate one of the zeros. Then, find all remaining Zeros. All non- integer zeros must be written as improper fractions. You must show all work & checks for these! (c) Write the polynomial in factored form. (d) Sketch the graph of the polynomial. (You must include the y-intercept, all zeros, any relative

minima/maxima, and the basic shape using the Leading Coefficient Test).1.)
