Analyze the polynomial function f x x 3 x 7 using parts a through e The graph of f behaves like y for large values of Ix b Find the x and y intercepts of the graph of the function The x intercept s is are Simplify your answer Type an integer or a fraction Use a comma to separate answers as needed Type each answer only once The y intercept is Simplify your answer Type an integer or a fraction 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 inter The zero s of f is are Simplify your answer Type an integer or a fraction Use a comma to separate answers as needed Type each answer only once so the graph of f The lesser zero is a zero of multiplicity the x axis at x the x axis at x The greater zero is a zero of multiplicity so the graph of f
