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.
