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.

1) x ∈ R

{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 }

sure i'm up for it
