**How To Find A Domain Of A Relation**. (a, b) ∈ r} and range (r) = {b : (a, b) ∈ r} the domain of relation from a to b is a subset of a.

3x = y;x,y ∈ a} ∴ r ={(1,3),(2,6),(3,9),(4,12)} the domain of r is the set of all first elements of the ordered pairs in the relation. 3x−y = 0;x,y ∈ a} i.e., r = {(x,y):
