Given regular languages L1 and L2, we know that L(M1) ∪ L(M2) is regular also. The proof in class used the fact that every regular language is recognized by a DFA and gave, for any two DFAs M1 and M2 a construction for a DFA that recognizes L(M1) ∪ L(M2). Your task is, using the fact that every regular language is recognized by an NFA, to come up with a alternate proof for “Given regular languages L1 and L2, L(M1) ∪ L(M2) is regular also.” You are not permitted the use of DFAs in your argument.
