Do you want to convert to interval notation?

If so, then take note that the first sign is a "less than or equal to" sign. So this means that the left brace will be a bracket [. Since the second sign is a "less than" sign, this means that the next brace is a right parenthesis ).

So the compound inequality in interval notation is:

[

Also, the answer in set-builder notation is

Here's the graph of the solution set

Note:
There is a closed circle at which means that we're including this value in the solution set
Also, there is an open circle at which means that we're excluding this value from the solution set.
