(a) Give the centre c and the radius r of S = B(0,5) B(3, 4). (b) Which of the following are neither open nor closed subsets of Y = (0,7]. V₁ = (0,2], V₂ = [5,7), V3 = (4,7], V₁ = (3,6], V = (2,17/2). (c) Let M = R. Using interval notation, give a simplified expression for the set L = [B(3, 1) UB(7,1)] n B(5,2).
