Question

What is the range of relation {(1, 2), (2, 4), (3,1), (4, 3)}

Answer 1

I think it’s 2,4,1,3 I’m not completely sure tho

Answer 2

2, 4, 1, 3
??? If I’m right, it’s that, bc you count only the elements “used” by the relation or function constitute which is the second part of the elements {2,4,1,3}
