Question

Represent all possible one-one functions from the set A = {1, 2} to the set B = {3,4,5} using arrow diagram.

Answer 1

Answer:

In the given arrow diagram, the element 'a' of set A is associated with two elements, ... Since, R = {(3, 6); (4, 7); (5, 8)} then Domain (R ) = {3, 4, 5} = A ... then f(1) = 3 × 1 + 2 = 3 + 2 = 5
