Which compound inequality is represented by the graph?

–3 ≤ x < 1
–3 < x ≤ 1
x ≤ –3 or x > 1
x < –3 or x ≥ 1

We are given a graph of compound inequality.

Given options are :

–3 ≤ x < 1

–3 < x ≤ 1

x ≤ –3 or x > 1

x < –3 or x ≥ 1.

In the graph, we can see that we have a solid dot on -3 and a hollow dot on 1.

Please note: A solid dot represents ≤ or ≥ inequality sign, because the number also included on which we have a solid dot.

And a hollow dot represents only < or > inequality sign.
