Q)
I. A relation $R_1$ from $A_1$= {1, 4, 9} to $B_1$ = (−3, −2, −1, 1, 2, 3} is defined as $R_1$ = $ \{(x, y):
x =y^2$ and $x \in A_1, y \in B_1\}$. \[\]II. A relation $R_2$ from $A_2$ = {9, 16, 25, 36} to $B_2$ = {−4, −3, 5, 6} is defined as $ R_2 = \{(x, y) : x = y^2$ and $x \in A_2, y \in B_2\}.$ \[\] III. A relation $R_3$ from $A_3$ = {3, 4, 5} to $B_3$ = {1, 5, 6} is defined as $R_3 = \{(x, y): x $ and y are
co-prime, where $x \in A_3, y \in B_3\}$. \[\] IV. A relation $ R_4$ from $A_4$ = {2, 3, 9} to $ B_4$ = {3, 4} is defined as $R_4 = \{(x, y) : x$, and y are
co-prime, where $x \in A_4, y \in B_4\}.$
