(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 = {3, 4, 5, 6} and R = {(a, b) : a, b ϵ A and a
(i) Write R in roster form.
(ii) Find: dom (R) and range (R)
(iii) Write R–1 in roster form
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.
