Answer:
{-3,1,2,5}
Step-by-step explanation:
Given that a set contains an ordered pair (x,y) such that x = domain of the relation while y = range of the relation
.
Here x can have two or more than two ranges which mean a value of x can have two or more than two images.
So the domain of the given relation R will contain the first elements from each ordered pair.
Therefore, the domain will be {-3, 5, 1, 2}.
(omitting one 5 since its occurring twice)
