Consider the function f which is given on its domain (0, oo) by f(x) = 8x - (24x + 9) In(x) . Find the number c in the domain of f at which f" is zero or undefined and give its exact value in the first column of the table below. The second column consists of several drop-down menus. Do the following: for each of the given intervals, state if the graph of f is concave up or concave down on that interval; state whether or not c is an inflection point of the graph of f. behavior 0 Click for List
