To find:

Answer to Problem 72RE
Local minimum at
Explanation of Solution
Given information:
Calculation:
For find local maxima or
For critical point of function
For critical point
From this only
Hence function has one critical point
Now sign of f’(x) on both side of
So value of derivative at
Value of derivative at
So f’(x) changing sign from negative to positive. So there is a local minimum at
