Let f(x)=8(x-4)2/3 +2.(A) Find all critical values and list them below. Note: If there are no critical values, enter 'NONE'.(B) Use interval notation to indicate where f(x) is increasing.Note: Use 'INF' for co, '-INF' for -oo, and use 'U' for the union symbol.Increasing:(C) Use interval notation to indicate where f(x) is decreasing.Decreasing:(D) List the values of all local maxima of f. If there are no local maxima, enter 'NONE'I values of local maximums =(E) List the values of all local minima of f. If there are no local minima, enter 'NONE'.values of local minimums =
