Consider the polynomial function $g (x) = - x^{5} - 9 x^{3} - 8 x .$ Factor $g (x)$ completely and determine all of its complex zeros. Which of the zeros of g are not x-intercepts of the graph of $y = g (x) ?$ Why do these zeros not correspond to a point on the x-axis? In general, what can be said about the similarities and differences between the zeros and the x-intercepts of the graphs of polynomial functions?
