Find all relative extrema of the function. (If an answer does not exist, enter DNE.)
relative maximum  (x, y)  = 



relative minimum  (x, y)  = 
Finding f’(x)
To find the relative extremum points of the function, we must use first derivative of the function,
Finding all the critical points and all points where f is undefined.
The critical points of a function f are xvalues within the domain of f for which f’(x) = 0 or
Where the function is defined and its derivative is zero and undefined.
So, critical points are:
