#R:{ -5, -4, 2}#

Explanation:

The range is the number on the right (the #y# coordinate)

#(3, color(red)(-5)), (1, color(red)(2)), (-1,color(red)( -4)), (-1,color(red)2)#

The range are #color(red)(-5), color(red)2, color(red)(-4), color(red)2#

If there's a repeated number write it once

Regarange the numbers from least to greatest

#R:{ -5, -4, 2}#
