(10 points) Consider the DFA, M, whose state diagram is given by: a b b 91 93 a 90 b a a 92 94 b a) Describe the language L(M). b) If we L(M), will the string obtained by swapping a's and b's in w also be in L(M)? Explain your answer. c) If w E L(M), will the string wR (the reverse of w) also be in L(M)? Explain your answer d) Describe in your own words the role of each of the states. e) Write a regular expression that describes L(M). (please explain your reasoning.) f) For c and d, if your answer is no, give a DFA that descibes the language obtained by applying that operation (swapping a's and b's or reversing) to all elements of L(M) Can you create a NFA for L(M) that uses fewer states? *
