(A) Use interval notation to indicate where f(x) is increasing.Note: Use 'INF' for oo, '-INF' for -oo, and use 'U' for the union symbol.Increasing:(B) Use interval notation to indicate where f(x) is decreasing.Decreasing:(C) List the values of all local maxima of f. If there are no local maxima, enter 'NONE'values of local maximums =(D) List the values of all local minima of f. If there are no local minima, enter "NONE"values of local minimums =f(x) = 4x² - 4x
