(a) Use a graphing utility to graph f(x)=x3-4x+2 on the interval [-2,2] and approximate any local maxima and local minima, (b) Determine where f is increasing and where it is decreasing. (a) Using a graphing utility, graph the function for -2sxs2 and -4sys 10. Choose the correct graph, below. OA. G The local maximum is y and it occurs at x (Round to two decimal places.) The local minimum is y and it occurs at x= (Round to two decimal places.) (b) Where is the graph of f increasing? O [-1.15,1.15] O [-2,-1.15] and [1.15,2] O 1-2-1.15] and [-1.08,5.08] O [-1.08,5.08] Choose the answer that most completely answers the question.) Where is the graph of f decreasing? O B. Q Q
