If `A={1,2,3}, B = {1,2}` then the number of functions from A to B are

If A={1,2,3) and B={a,b} , then the number of functions from A to B is

A={a, b, c},B={1,2} then the number of relations from A to B is

If A={1,2,3},B={1,2,3,4,5,6,7,8} then the number of functions f from A to B such that f(i)lt=f(j) AAiltj

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

If A={2,4} , B={1,3,5} . Then the number of relations from A to B is …….

Let A = {1,2,3} and B = {a,b,c}. If l is the number of functions from A to B and m is number of one-one functions from A to B, then (A) l is 9 (B) m is 9 (C) l is 27 (D) m is 16

If f:A rarr B,A={1,2,3,4},B={1,2,3} and f(i)!=i then the number of onto functions from A to B is
