1. Let L be any language. We define I = {reverse(x)/x 2 L). (For example, if L = {b, baa, aaabb, aabba}, then L = {b, aab, bbaaa, abbaa}.) (a) Prove that for any language L, if there is an FA that accepts L, then there is a TG that accepts L'. (b) Prove that for any language L, if there is a TG that accepts L, then there is a TG that accepts Lº.
