# 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

**Solution:**

From the given data in the problem, we have

A = {1, 2, 3, 5},

B = {4, 6, 9} and

The relation from A to B is given as:

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

Therefore,

R in roster form can be written as

R = {(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.

**Summary:**

A = {1, 2, 3, 5} and B = {4, 6, 9} is given. We have found that R = {(1, 4), (1, 6), (2, 9), (3, 4), (3, 6), (5, 4), (5, 6)}
