Question

If A=(1 2 3 5) and B=(4 5 6) then which of the following is the function of A to B?

A. {(1,2), (2,4), (3,4), (5,4)}
B. {(1, 4) (2, 5), (3, 6)}
C. {(4, 1), (5, 2), (6, 3)}
D. {(1, 4), (3, 5), (5, 5)}​

Answer 1

Answer:

here is your answer

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 R

1

consists of elements form both A×B and B×A.

Thus R

1

is not a relation from A to B.

Answer 2

Answer:

(1,4), (2,4), (3,4), (5,4)
