Questions 1 relate to the following constrained optimization
problem: maximize z(x,y)=4x^2-2xy+6y^2 subject to x+y=72. subject
to . A) What is the optimal value of X?
B) What is the optimal value of Y?
C) What is the maximized value of Z?
Given function f(x,y,z)=x^(2)+2*y^(2)+z^(2), subject to two
constraints x+y+z=6 and x-2*y+z=0. find the extreme value of
f(x,y,z) and determine whether it is maximum of minimum.
