Answer:
{2, 3, 8}
Step-by-step explanation:
Domain is the of set all x-coordinates of the ordered pair in the relation.
As per the statement:
Given the relation:
R: ={(3, 5), (8, 6), (2, 1), (8, 6)}
Since, the ordered pair is in the form of (x, y)
x-coordinates are 3, 8, 2
y-coordinates are: 5, 6, 1
By definition of domain:
Domains of the following relation R is, {2, 3, 8}
