Which compound inequality is represented by the graph?


–3 ≤ x < 1

–3 < x ≤ 1

x ≤ –3 or x > 1

x < –3 or x ≥ 1

Which compound inequality is represented by the graph? 3 x lt; 1 3 lt; x 1 x 3 or x gt; 1 x lt; 3 or x 1 class=

Verified Answer :

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.

Graph represents greater than or equal to -3 and less than 1 value.

Therefore, correct option is  –3 ≤ x < 1.

Option (a) is correct as the compound inequality \(\boxed{ - 3 \leqslant x < 1}\) represented by the graph.


Further explanation:

There are two types of the interval close interval and open interval.

If the values of \(x\) doesn’t includes the number than it is represented by hollow dot on the number line and if the values of \(x\) includes the number than it is represented by the solid dot on the number line.


Given:

The compound inequalities are listed below.

(a). \(- 3 \leqslant x < 1\)

(b). \(- 3 < x \leqslant 1\)

(c). \(x \leqslant  - 3{\text{ or }}x > 1\)

(d). \(x <  - 3{\text{ or }}x \geqslant 1\)


Explanation:

From the number line it is shown that -3 is included in the value of x as it is shown by solid dot and 1 is not included as it is shown by hollow dot.

The value of x lies between -3 to 1.


Option (a) is correct.

Option (b) is not correct.

Option (c) is not correct  

Option (d) is not correct.


Hence, Option (a) is correct as the compound inequality \(\boxed{ - 3 \leqslant x < 1}\) represented by the graph.
