Question

Dados os conjuntos A = { 0,1,2,3} e B = { 0,1,2,3,4,5}, determine as relações de A em B que são funções :
a ) R1 = {(0,2),(1,3),(2,4),(3,5)}
b ) R2 = {(0,3),(1,3),(2,3),(3,5)}
c) R3 = {(0,1),(0,2),(1,1),(1,2),(2,1),(2,2),(3,1),(3,2)
d) R4 = {(0,4),(1,5),(2,0)}

Answer 1

{(0,0) (0,1) (0,2) (0,3) (0,4) (0,5) (1,0) (1,1) (1,2) (1,3) (1,4) (1,5) (2,0) (2,1) (2,2) (2,3) (2,4) (2,5) (3,0) (3,1)(3,2) (3,3) (3,4) (4,5)
