A Sketch the graph on the coordinate plane to the right Mark and label any relative extrema as relative maximum or " relative minimum How many relative extrema does the graph of this quartic function have ? elative maximum ( s ) relative minimum ( s ) total relative extrema B . Vary a b c , d and fto explore other quartic functions . What is the maximum number of relative extreme for a fourth- degree polynomial function C . Does a fourth- degree polynomial function ever have any absolute extrema ? Explain
