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}
