Answer
$(-\infty,-1)\cup[2,\infty)$.
The graph is shown below.
Work Step by Step
The given compound inequality is
$x\geq2$ or $x\lt-1$.
First graph then take the union of the two inequality.
The graph is shown in the image file.
We can write the compound inequality.
$x\geq2$ as $[2,\infty)$ and $x\lt-1$ as $(-\infty,-1)$
The union is
$(-\infty,-1)\cup[2,\infty)$.
