If there are more than one, enter them separated by commas. Critical value(s) = (B) Use interval notation to indicate where at) is increasing. Note: When using interval notation in WeBWorK, you use I for 00, -l for oo, and U for the union symbol. If there are no values that satisfy the required condition, then enter "D" without the quotation marks. Increasing: (C) Use interval notation to indicate where f(z) is decreasing. Decreasing- (D) Find the w-coordinates of all local maxima of f. If there are no local maxima, enter -1000. If there are more than one, enter them separated by commas. Local maxima at z = E] (E) Find the ar-coordinates of all local minima of f. If there are no local minima, enter 1000. If there are more than one, enter them separated by commas. Local minima at a: = (F) Use interval notation to indicate where f(w) is concave up. Concave up: (oo,0) U (1.8,oo) (G) Use interval notation to indicate where f(:::) is concave down. Concave down: (H) Find all inflection points of f. If there are no inflection points, enter -1000. If there are more than one, enter them separated by commas. Inflection point(s) at a
