Answer: -2 < x < 2
Step-by-step explanation:
The number line represents an inequality. You can tell this because it has a set of values that would work, represented by the teal. Since there are dots at -2 and 2, and the shading is in between these two points, you can conclude that the inequality (for variable x) is -2 < x < 2 OR -2 <= x <= 2. Looking once more at the dots denoting the endpoints of the inequality, the dots are open. When graphing inequalities, open dots mean exclusive )< or >) and closed dots mean inclusive (<= or >=). Therefore the inequality is -2 < x < 2.
