Analyze the polynomial function The y intercept s is are 21 Simplify your answer Type an integer or a fraction Use a comma to separate answers as needed Type each answer only once c Determine the zeros of the function and their multiplicity Use this information to determine whether the graph crosses or touches the x axis at each x intercept The real zero s of f is are 7 3 7 Simplify your answer Type an integer or a fraction Use a comma to separate answers as needed Type each answer only once A Answer parts a through h The least zero is of multiplicity 1 so the graph of f crosses the x axis at x graph off crosses the x axis at x 7 d Use a graphing utility to graph the function The graphs are shown in the viewing window Xmin 5 B 7 The middle zero is of multiplicity 1 so the graph of f crosses the x axis at x 3 The greatest zero is of mult 10 Xmax 10 Xscl 1 Ymin 50 Ymax 50 Y sci 5 Choose the correct graph below O C Q O D o O 5
