Consider the cone C = {x = R | a'x 0, i = 1,...,m} and assume that the first n constraint vectors a,..., an are linearly independent. For any nonnegative scalar r, we define the polyhedron P, by P = { x =C | x=r} i=1 (a) Show that the polyhedron P, is bounded for every r 0. (b) Letr> 0. Show that a vector x P, is an extreme point of P, if and only if x is an extreme ray of the cone C.
