Question

Dados os conjuntos A= {-2, -1, 0, 1, 2, 3} e B= {0,1,2,3,4} e a relacao R= {(x,y) e A X B I y = x +2} determine a relacao em forma de pares ordenados

Answer 1

A x B = {(-2,0),(-2,1),(-2,2),(-2,3),(-2,4),(-1,0),(-1,1),(-1,2),(-1,3),(-1,4),(0,0),(0,1),(0,2),(0,3),(0,4),(1,0),(1,1),(1,2),(1,3),(1,4),(2,0),(2,1),(2,2),(2,3),(2,4),(3,0),(3,1),(3,2),(3,3),(3,4)}

R = {(x,y) ∈ A X B/ y = x + 2}, portanto,
R = {(2,0),(-1,1),(0,2),(1,3),(2,4)}
