The domain of the absolute value function is the set of real numbers

The domain of a function is the set of input values the function can take

From the figure, we can see that the lines of the absolute value function extend in both directions of the x-axis

This means that, the function can take any of the x-values as its input i.e all real numbers

Hence, the domain of the absolute value function is the set of real numbers
