Exercise (b) Find the local minimum and maximum values of f Step 1 We know f(x) changes from increasing to decreasing at x = 4 herefore, fT 8V2 is a maximum maximum. Step 2 e know f(x) changes from decreasing to increasing at x = L. Therefore, is a minimum So, the local minimum and maximum values of f are as follows local minimum value-8/2 local maximum value0 kip (you cannot come back)
