Find the inverse of the given relation.

{ (3,1), (3,1), (7,-7), (12,-15) }

A.{ (1,3), (3,1), (-7,7), (12,-15) }

B.{ (1,3), (1,3), (-7,7), (-15,12) }

C.{ (1,3), (1,3), (-7,-7), (-15,12) }

D.{ (1,3), (-1,-3), (-7,7), (-15,12) }

The answer is B.

Step-by-step explanation:

To obtain the inverse of a relation you simply interchange the x and y coordinates of each pair.

Here:

(3,1) becomes (1,3)

(3,1) becomes ((1,3)

(7, - 7) becomes (-7,7) and

(12, - 15) becomes (-15, 12)
