Consider the functions f(x) = x* +8x% ,g(x) = in_ a. 9 Find the x-intercepts and y-intercepts for the graph (Specify which are x- intercepts and which are y-intercepts) Find any critical points for the graph and the intervals on which the graph is increasing and those on which 1t 1s decreasing. . Find any inflection points for the graph and the interval on which the graph 1s concave upward and those on which it 1s concave downward. Sketch the graph (Label all the intercepts, local extrema and points of inflection)
