Question

if a= (1235) and B = (456) then which of the following is a functional from A to b​

Answer 1

Step-by-step explanation:

A relation from A to B will include elements from A×B

Elements of A×B are

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

Now the relation R1 consists of elements form both A×B and B×A.

Thus R1 is not a relation from A to B.
