What is the domain of the relation?

domain is all the "x" values. What are the options for the x-coordinates in your graph? everything! So, the x-coordinates are all real numbers.
Answer: 1) x ∈ R
Answer: {x | x ∈ R }
Step-by-step explanation:
From the given graph, it can be see that it is a line y=2 parallel to x axis.
i.e. For every x value, the y-value is constant as y=2.
Also, for any straight line , the domain of the relation is given by :-
Domain= Set of real values = {x | x ∈ R }
Hence, the domain of the relation = {x | x ∈ R }
