Domain = {2 , 4 , 8 , 1 , -5}
Explanation:
Domain of any relation is the set of the elements of all the ordered pairs which are of the set from which the relation is laid out.
In simpler words , you just need to write the first members of all the ordered pairs.
As in this case :-
in the ordered pair (2, 0)
2 is the domain as it is the starting of the ordered pair.
Similarly 4 , 8 , 1 , -5 are the domains of other ordered pairs.
Now you just need to write them in the curly brackets separated by comma.
Here's your answer!
