Question

Assume f= {(1,2), (5,7), (9, 12), (10,10)}. Find the inverse.{(2,1), (7,5), (12,9), (10,10)}{(2,1), (7,5), (12,9) }{(10, 10)}This set of ordered pairs does not have an inverse function.

Answer 1

To find the inverse, exchange the coordinates of the ordered pairs.

So the inverse of the relation is: {(2,1), (7,5), (12,9), (10,10)}

Finally we obtain that the correct answer is the second option.
