Suppose that .

(A) List all the critical values of . Note: If there are no critical values, enter 'NONE'.

(B) Use interval notation to indicate where is increasing.
Note: Use 'INF' for , '-INF' for , and use 'U' for the union symbol.
Increasing:

(C) Use interval notation to indicate where is decreasing.
Decreasing:

(D) List the values of all local maxima of . If there are no local maxima, enter 'NONE'.
values of local maximums =

(E) List the values of all local minima of . If there are no local minima, enter 'NONE'.
values of local minimums = (F) Use interval notation to indicate where is concave up.
Concave up:

(G) Use interval notation to indicate where is concave down.
Concave down:

(H) List the values of all the inflection points of . If there are no inflection points, enter 'NONE'.
values of inflection points =

(I) Use all of the preceding information to sketch a graph of . When you're finished, enter a "1" in the box below.
