Consider the function f(x,y,z) = x2 â y2 + z2 subject to the constraint x + 4z = 5
(a) f need not have an absolute maximum nor absolute minimum because x + 4z = 5 is a plane, which is not compact. Show that, in fact, f does not have an absolute minimum.
(b) f does have an absolute maximum. Use Lagrange multipliers to find where f has its absolute maximum.
