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 -9%3C=x%3C-4 in interval notation is:

[)


Also, the answer in set-builder notation is


Here's the graph of the solution set

Graph of the solution set

Note:
There is a closed circle at x=-9 which means that we're including this value in the solution set
Also, there is an open circle at x=-4 which means that we're excluding this value from the solution set.
