3. Given a nonempty polyhedron P = {(x, y) = R R: Ax + By b}, let Q denote its projection onto x-space, i.e., Q = {x = Rn: 3y Rk, Ax + By b}. = Prove or disprove the following statements by counterexamples: 1) Suppose that (, ) is an extreme point of P. Is an extreme point of Q? 2) Suppose that is an extreme point of Q. Does there exist a such that (, ) is an extreme point of P? 3) Suppose that is an extreme point of Q and P does not contain a line. Does there exist a such that (, ) is an extreme point of P?
