Question
If A = {1, 2, 4} and B = {1, 2, 3}, represent following sets graphically:
A × B
A × B
✓
Answer
We have, A = {1, 2, 4} and B = {1, 2, 3} $\therefore$ A × B = {1, 2, 4} × {1, 2, 3} = {(1, 1), (1, 2), (1, 3), (2, 1), (2, 2), (2, 3), (4, 1), (4, 2), (4, 3)} Hence, we represent A on the horizontal line and B on vertical line. Graphical representation of A × B is as shown below:
