Question

f:R->R where f(x) = x
domain, range, co-donan, graph, aro diagram .

​

Answer 1

Answer:

Since, R = {(3, 6); (4, 7); (5, 8)} then Domain (R) = {3, 4, 5} = A

We observe that no two ordered pairs in R have the same first component.

Therefore, R is a mapping from A to B.

(ii) Let A = {1, 2, 3} and B= {7, 11} and R = {(1, 7); (1, 11); (2, 11); (3, 11)}
