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