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» 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} ∴ R = { (1, 4), (1, 6), (2, 9), (3, 4), (3, 6), (5, 4), (5, 6) } |
