The domain of the graph is {x : x∈ R}
How to determine the domain?
The domain of a function or graph is the set of input values the function can take.
This in other words represents the x values
From the graph, we can see that x values extend indefinitely on both axes.
This is indicated by the arrows at the ends of the curve
This means that the domain is the set of all real numbers
Hence, the domain of the graph is {x : x∈ R}
