(A) Find all critical values of , compute their
average, and enter it below.
Note: If there are no critical values, enter -1000.
Average of critical values =

(B) Use interval notation to indicate where is increasing.

Note: When using interval notation in WeBWorK, remember
that: You use 'I' for and '-I' for .
Enter 'U' for the union symbol. If you have extra boxes, fill each in with an 'x'.

Increasing:

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

(D) Find the -coordinates of all local maxima of ,
compute their average, and enter it below.
Note: If there are no local maxima, enter -1000.

Average of values =

(E) Find the -coordinates of all local minima of ,
compute their average, and enter it below.
Note: If there are no local minima, enter -1000.

Average of values =

(F) Use interval notation to indicate where is concave up.
Concave up:

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

(H) Find all inflection points of , compute their
average, and enter it below.
Note: If there are no inflection points, enter -1000.
Average of inflection points =
