Answer the following questions about the function whose derivative is f'(x) = (x - 1)^2 (x+ 3). What are the critical points of f? On what open intervals is f increasing or decreasing? At what points does f assume local maximum and minimum values?
Find the critical points, if any. Select the correct choice below and, if necessary, fill in the answer box to complete your choice.
The critical point(s) of f is/are X =
(Simplify your answer. Use commas to separate answers as needed.)
The function has no critical points.
Determine where f is increasing and decreasing: Select the correct choice below and fill in the answer box to complete your choice.
The function is increasing on the open interval(s) and decreasing on the open interval(s).
The function is decreasing on the open interval(s) and never increasing.
The function is increasing on the open interval(s) and never decreasing.
Determine the local maximum, if any. Select the correct choice below and, if necessary, fill in the answer box to complete your choice.
x =
(Simplify your answer. Use commas to separate answers as needed.)
There is no local maximum.
