Please refer to the attached image for the graph

Step-by-step explanation:

Given:

[tex]2x +1 > 3 \text{ or } 2x -1 < -3[/tex]

Let's solve for the [tex]2x +1 > 3[/tex] part of the Compound Inequality first.

[tex]2x +1 > 3 \\ 2x > 3 -1 \\ 2x > 2 \\ x > \frac{2}{2} \\ x > 1[/tex]

Now, let's solve [tex]2x -1 < -3[/tex]:

[tex]2x -1 < -3 \\ 2x < -3 +1 \\ 2x < -2 \\ x < \frac{-2}{2} \\ x < -1[/tex]

We can now rewrite our Compound Inequality as [tex]x > 1 \text{ or } x < -1[/tex]
