Answer

$A \times B$ = {(1, -3), (1, -2), (1, -1), (1, 0), (2, -3), (2, -2), (2, -1), (2, 0), (3, -3), (3, -2), (3, -1), (3, 0)}

Work Step by Step

We are asked to give the cross products of two sets $A$ and $B$. This means we have to come up with ordered pairs that have the first element of the ordered pair in $A$ and the second element of the ordered pair in $B$. $A \times B$ = {(1, -3), (1, -2), (1, -1), (1, 0), (2, -3), (2, -2), (2, -1), (2, 0), (3, -3), (3, -2), (3, -1), (3, 0)}
