Question 2

reflexive, Symmetric, Transitive and anti-symmetric

Q#01:  Let X = { 1, 5, 9} , Y =  { 3, 4, 7}

            Define f : X →Y by  f(1) = 4,  f(5) = 7, f(9) = 4

(i)                 Is f one-one?

(ii)               Is f onto?

(iii)             Does inverse of f exist?                                                       

Q#02: Let A = {a, b, c} and R = {(a, c), (b, b), (c, a)} be a relation on A.

 Determine whether R is reflexive, Symmetric, Transitive and anti-symmetric, or not. 

                                                                                                           

Q#03: Find the 36th term of the arithmetic sequence whose 3rd term is 7 and 8th term is 17.

Please provide solution.

NFA/FA

Q. No. 1 Construct Non-Deterministic Finite Automaton (NFA) from the concatenation of the following two languages:                                         

                                                           

a. Language of all strings defined over Σ = {0, 1} whose length is even and number of 1’s are odd.

b. Language of all strings defined over Σ = {0, 1} whose second last letter is 1.

Hint: First construct FA for the given languages and then construct NFA from their concatenation.                                                                                 

Q. No. 2 Construct a Finite Automaton (FA) for the language of all strings defined over Σ = {0, 1} that ends with substring “01” and have odd length.
