Suppose that re) = We + 3W3 [A] Find all critical values of f. If there are no critical valuesr enter None. If there are more than one, enter them separated by commas. Critical valueis] = D {B} Use interval notation to indicate where x) is increasing. Note: When using interval notation in WeBWorK, you use lfor 00, -l for oo. and U for the union symbol. If there are no values that satisfy the required condition, then enter "{}" without the quotation marks. Increasing: Li [C] Use interval notation to indicate where x) is decreasing. Decreasing: C] [Di Find the intcoordinates of all local maxima off. If there are no local maxima, enter None. If there are more than oneI enter them separated by commas. Local maxima at m = D {E} Find the tit-coordinates of all local minima of f. If there are no local minimar enter None . If there are more than one, enter them separated by commas. Local minima at s: 2 C] [F] Use interval notation to indicate where x) is concave up. Concave up: U [(3) Use interval notation to indicate where x) is concave down. Concave down: D {H} Find all inflection points of f. If there are no inflection points, enter None . If there are more than one, enter them separated by commas. lnflection pointls} at m = C] (I) Use all of the preceding information to sketch a graph of f.
