Suppose that [math]

(A) Find all critical values of [math]. If there are no critical values, enter -1000. If there are more than one, enter them separated by commas.
Critical value(s) =

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

Note: When using interval notation in WeBWorK, you use I for [math], -I for [math], and U for the union symbol. If there are no values that satisfy the required condition, then enter (0,0) .

Increasing:


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


(D) Use interval notation to indicate where [math] is concave up.
Concave up:


(E) Use interval notation to indicate where [math] is concave down.
Concave down:


(F) Find all inflection points of [math]. If there are no inflection points, enter -1000. If there are more than one, enter them separated by commas.
Inflection point(s) at [math] =
