1.	A = {1, 2, 3, 5} and B = (4, 6, 9}. Define a relation R from A to B by R = {(x, y): the difference between x and y is odd; x ∈ A, y∈ B}. Write R in roster form.
Answer» Given A = {1, 2, 3, 5} and B = {4, 6, 9} R = {(x, y): the difference between x and y is odd; x ∈ A,y ∈ B} = {(1,4), (1, 6), (2, 9), (3, 4), (3, 6), (5,4), (5, 6)}

A = {1, 2, 3, 5} and B = (4, 6, 9}. Define a relation R from A to B by R = {(x, y): the difference between x and y is odd; x ∈ A, y∈ B}. Write R in roster form.

Answer»

Given A = {1, 2, 3, 5} and B = {4, 6, 9}

R = {(x, y): the difference between x and y is odd; x ∈ A,y ∈ B}

= {(1,4), (1, 6), (2, 9), (3, 4), (3, 6), (5,4), (5, 6)}
