Hello, please help me to find the maximum and minimum of the following objective function (if they do exist) if there's no maximum state the reason.
then I'm given a graph with these points
I would say the maximum is 24 at the points (0,6) however, that's wrong, according to my textbook, there's no maximum, why????
concerning the minimum, I agree with my textbook, the minimum is 10 at the points (2,1)
