6z-2 f(1) = I+2 (A) Find all critical values of f. If there are no critical values, enter -1000. If there are more than one, enter them separated by commas. Critical value(s) = -1000 (B) Use interval notation to indicate where f(z) is increasing. Note: When using interval notation in WeBWork, you use I for o, 4 for -00, and U for the union symbol. If there are no values that satisfy the required condition, then enter "f" without the quotation marks. Increasing: -2 (C) Use interval notation to indicate where f(z) is decreasing. Decreasing: -21 (D) Find the I-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) Find the I-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 z = (F) Use interval notation to indicate where f(r) is concave up. Concave up:
