we have the function
[tex]r(x) = |x - 2| - 1[/tex]
using a graph tool
see the attached figure
The domain of the function is all real numbers
the domain is the interval---------> (-∞,∞)
The range of the function is [tex]r(x) \geq -1[/tex]
the range is the interval -------> [-1,∞)
The graph in the attached figure
