**(i)** {(x, x2) : x is a prime number less than 10}. Roster form: R = {(1, 1), (2, 4), (3, 9), (5, 25), (7, 49)}

**(ii)** The domain of R is the set of first co-ordinates of R

Dom(R) = {1, 2, 3, 5, 7}

The range of R is the set of second co-ordinates of R

Range(R) = {1, 4, 9, 25, 49}

Answered by Sakshi | 3 months agoLet R = {(a, b) : a, b, ϵ N and a < b}.Show that R is a binary relation on N, which is neither reflexive nor symmetric. Show that R is transitive.

Let A = (1, 2, 3} and B = {4} How many relations can be defined from A to B.

If A = {5} and B = {5, 6}, write down all possible subsets of A × B.
