Must be finite May be infinite The language generated by a regular grammar. Must be finite May be infinite The set of nonterminals in a regular grammar.

Prove that a disjoint union of any finite set and any countably infinite set is countably infinite. Proof: Suppose A is any finite set, B is any countably infinite set, and A and B are disjoint. By definition of disjoint, A ∩ B = ∅ Then h is one-to-one because f and g are one-to one and A ∩ B = 0. Further, h is onto because f and g are onto and given any element x in A ∪...
6. Let X be an infinite set and let U = {0}U{A CX :X \ A is finite}. (a) Prove that U is a topology on X. (b) Let B be an infinite subset of X. What is the set of limit points (also known as "accumulation points") of B? (c) Let B be a finite subset of X. What is the set of limit points of B?
5-8 please Consider the following dozen infinite sets comparisons. Write down >, < or = between each pair of sets to indicate their relative size. SET #1 SET #2 1: {1,2,3,4,...} all natural numbers) The natural numbers starting with 3] {3,4,5,6,...} {1,2,3,4,...} (all natural numbers) (All even natural numbers] {2,4,6,8,...} {1,2,3,4,...} all natural numbers All odd natural numbers) {1,3,5,7,...} {1,2,3,4,...} (all natural numbers] All unit fractions) {1,1/2, 1/3,1/4,...} {1,2,3,4,...} (all natural numbers) All points on an infinite line] (All points...
Question 7 Classify each of the following sets as finite, countable infinite, or uncountable (no proof is necessary): A=0 B = {2 ER: 0 < x < 0.0001} C=0 D=N E = {R} F= {n EN:n <9000} G=Z/5Z H = P(N) I= {n €Z:n > 50 J=Z Bonus: Give an example of a set with larger cardinality then any of the above sets.
