Question

Determine the domain and range and whether

the relation is a function:
{(1,2) (3,3) (4,1) (6,2) }

Answer 1

The domain are your X values(1, 3, 4, 6) and your range is your Y values (2, 3, 1, 2)

This is a function and that is because every X has only one Y.
It is okay for your Y values to have same numbers, but it is not a function if your X values are repeated/the same

Hope this helps :)
