Answer:
-3, -2, 2, 3
Step-by-step explanation:
First, remember the definition of an integer number.
An integer number can be positive, negative or zero. This number has no digits after the decimal point (0.235, 0.8, 0.77), nor a fractional part ([tex]\frac{1}{4}, \frac{1}{8}, \frac{1}{4}, \frac{1}{2}, \frac{2}{3}, \frac{6}{7}[/tex]).
Therefore, the only option is the second set, since it has no fractional numbers.
