Let A = {1, 2, 3, 4, 5, 6}.

Define a relation R from A to A by R = {(x, y): y = x + 1}.


(i) Write R in roster form.


(ii) Find dom (R) and range (R).


(iii) What is its co-domain?


(iv) Depict R by using arrow diagram.


Given: A = {1, 2, 3, 4, 5, 6}


(i) R = {(x, y): y = x + 1}


So, R is Roster Form is,


R = {(1, 2), (2, 3), (3, 4), (4, 5), (5, 6)}


(ii) Dom(R) = {1, 2, 3, 4, 5}


Range(R) = {2, 3, 4, 5, 6}


(iii) Here, y = x + 1


So, the CoD(R) = {1, 2, 3, 4, 5, 6,………… }


(iv)
