1. Let d, be a metries on X#o and let the function d: X x XR defined by: da, y) 1+ di(1, 9) Vr. y € X. d(r, y) = prove that (X, d) is a metric space, 2. Determine whether the following subsets of R are the neighborhood of of the point 3 A = (1,5), B = {1,2,3, 4,5), N, Z. Q. 3. In R with the usual metric , find: (i) The interior of (2, 3) U (5, 6) (ii) The interior of (5,6) (iii) The limit point of (2,3) (Iv) The closure of the set (1+ n+1 4. Give an example to show that the equality may not hold in An BC An B.
