You do have square brackets to include the equal.
I'd start with -4, so I'd write
[-4, -1]

okay... but why is that the answer? I'm supposed to explain how i got the answer

Answer 5

You use the numbers of the beginning and end of the interval from left to right.
If the = is included, you use square brackets. If the = is not included, you use parentheses.

Including -4 and -1.
[-4, -1]
