Suppose that
(A) Find all critical values of .
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 is increasing.
Note: When using interval notation in WeBWorK, you use
I for , -I for , and
U for the union symbol. If there are no values that satisfy the
required condition, then enter "{}" without the quotation marks.
Increasing:
(C) Use interval notation to indicate where is decreasing.
Decreasing:
(D) Find the -coordinates of all local maxima of .
If there are no local maxima, enter -1000.
If there are more than one, enter them separated by commas.
Local maxima at =
(E) Find the -coordinates of all local minima of .
If there are no local minima, enter -1000.
If there are more than one, enter them separated by commas.
Local minima at =
(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) Find all inflection points of .
If there are no inflection points, enter -1000.
If there are more than one, enter them separated by commas.
Inflection point(s) at =
(I) Use all of the preceding information to sketch a
graph of . When you're finished, enter a "1" in the box
below.
