Let A = {1, 2, 3} and B = {3, 4}. Find A x B and show it graphically
given: A = {1, 2, 3} and B = {3, 4}
To find: graphical representation of A × B
A x B = {(1, 3), (1, 4), (2, 3), (2, 4), (3, 3), (3, 4)}
To represent A × B graphically, given steps must be followed:
a. One horizontal and one vertical axis should be drawn
b. Element of set A should be represented in horizontal axis and on vertical axis elements of set B should be represented
c. Draw dotted lines perpendicular to horizontal and vertical axes through the elements of set A and B
d. Point of intersection of these perpendicular represents A × B.
