Given information
The first derivative of the function is .
Step-by-step explanation
Step 1.
Increasing test:
If on an interval, then is increasing on that interval.
If on an interval, then is decreasing on that interval.
Find the critical points
Equate the first derivative to zero and solve for
Hence, the critical points are
