to graph f(x)=x-5x+4on 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 -2x2and-4sy10. Choose the correct graph, below. Q E OB. The local maximum is y 8.30 and it occurs at x -1.29. (Round to two decimal places.) The local minimum is y and it occurs at x (Round to two decimal places.) OC. a a
