Let A = {1,2} and B {3,4}. Find the number of relations from A to B.

Let A = {x, y,z} and B = {1,2}. Find the number of relations from A to B.

Let A = {1, 2}, B= {3, 4}, then the number of relations from A to B will be:

Let A={a,b,c} and B={1,2,3}. Find the number of relations from A into B.

Let A = {1, 2, 3, 4} and B = {x,y,z}. Let R be a relation from A into B defined by : R= {(1,x), (1,z), (3,x), (4,y)}. Find the domain and range of R.

If A = { 2, 3 } , B = { 2, 5 } , then the total number of relations defined from A to B is :
