Absolute Maximum/Minimum Values of Multivariable Functions - Part 1 of 2
To find absolute max/min values of a continuous function g on a closed bounded set D:

  1. Evaluate f at the critical points of f in D.
  2. Find the extreme values of f on the boundary of D.
  3. Pick the largest and smallest.

Example:
Find the absolute maximum and minimum of:
f(x,y) = 3 + xy - x - 2y; D is the closed triangular region with vertices (1,0), (5,0), (1,4).
