write the inverse S^-1 of the following relation: S= {(4,d), (u,a), (r,a), (2,5) (u,v)}?

3 ⤊

Respond by specifying S^-1 by extension....thanks

S^{-1} = { (d,4),(a,u),(a,r),(5,2),(v,u) }.

To get S^-1 simply interchange the components of
each ordered pair.
So
S^-1 = { (d,4),(a,u),(a,r),(5,2),(v,u) }.
