Sejam A = {1, 2} e B = {1, 2, 3, 4} quantas funções de A para B são crescentes ?
Se F(1) = 1, entao F(2) pode ser 1, 2, 3 ou 4.
Se F(1) = 2, entao F(2) pode ser 2, 3 ou 4.
Se F(1) = 3, entao F(2) pode ser 3 ou 4,
Se F(1) = 4, entao F(2) é 4.
Ai estao todas as 10 possibilidades de funcoes crescentes.
