Onto functions from A to A such that `f(i) ne i` for all `i`, is

Let A={1,2,3,4,5} and B={-2,-1,0,1,2,3,4,5}. Increasing function from A to B is

Let A={1,2,3,4,5} and B={-2,-1,0,1,2,3,4,5}. Non-decreasing functions from A to B is

Let A={1,2,3,4,5} and B={-2,-1,0,1,2,3,4,5}. Non-decreasing functions from A to B is

Let A={1,2,3},B=4,5,6,7} and let f={(1,4),(2,5),(3,6)} be a function from A to B. Show that f is one - one but not onto.

Let S={1,2,3,4). The number of functions f:S rarr S. such that f(i)<=2i for all i in S is

Let S = {1, 2, 3, 4). The number of functions f: S->S. Such that f(i) le 2i for all i in S is
