Answer 1

hey mate

here is the answer....

Answer:

As we know that the no two domain Should be same.i.e;-all the elements of the set A must be uniquely related to the elements of set B.

so, the no of ordered pair for the one such function would be 5.

but we know that a single element could be related to 5 elements of the set B.(not at the same time)

so ,the Maximum number of function could be 25. (5*5)

for example:

A={1,2}

B={1,2,3}

so,1st function can be B is 1st multiple of A.

A. B

1---1

2---2

and the second function could be that B is successor of A.

A. B

1---2

2---3
