Answer:
Absolute maxima an minma both occured at
.

Given function is,

subject to,
Let 
To find absolute maxima and absolute minima using Lagranges multipliers method consider
as the multipliers such that,


on compairing both side we get,



From (2),



Absolute maxima, at x=3, y=0,
is,

Absolute minima, at x=3, y=0,
is,

Hence the result.
