Write the absolute value inequality

Question

Team thermometer in a freezer is set at -2°F. This temperature varies up to 3°F throughout the day.

Answer 1

| T + 2 | <=3

OR

-5°F <= T <= 1°F

Note: I would assume that "up to" includes the value, hence my choice of "less than or equal". But you may disagree, or the actual question may be more specific.
