Answer: -1, 0, 1, 2, 3
Step-by-step explanation:
If we say the expression out loud, we say it as "m is greater than -2 but less than or equal to 3."
This is because < or > means less than or greater than. These don't include the given value.
≤ or ≥ means less than or equal to or greater than or equal to. These do include the given value/values.
In this equation, we don't include -2, but we include 3. That's why the included values are -1, 0, 1, 2, 3.
