Let A = {1, 2, 3, 5} AND B = {4, 6, 9}.

Question:

Let A = {1, 2, 3, 5} AND B = {4, 6, 9}.

Let $R=\{(x, y): x \in A, y \in B$ and $(x-y)$ is odd $\} .$

Write R in roster form.

 

Solution:

Given: $A=\{1,2,3,5\}$ AND $B=\{4,6,9\}$

$R=\{(x, y): x \in A, y \in B$ and $(x-y)$ is odd $\}$

Therefore, R in Roster Form is,

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