Inverse relation of `{(1,2),(1,3),(2,3)}` is

Is the relation R={(1,2),(1,3),(2,3),(3,2)} a function, defined on the set {1,2,3} ?

If A=(1,2,3), then the relation R={(1,1)(2,2),(3,1),(1,3)} is

The inverse of [(1,2),(2,3)] is

If A={1, 2, 3}, then the relation R={(1,1),(2,2),(3,1),(1,3)} , is

If A={1, 2, 3}, then the relation R={(1,1),(2,2),(3,1),(1,3)} , is

Find the inverse of f={(1,2),(2,3),(3,2)}

If A = {1,2,3} and consider the relation R = {(1,1), (2,2) , (3,3) , (1,2) ,(2,3), (1,3)} . Then R is .......

The relation R={(2,3),(1,1),(1,3),(3,1)} on the set A=(1,2,3) is______
