n is the set of integers that are greater than or equal to -1 and less than or equal to 2 write the set in roster form.

I am really confused on how to do this and what this means over al. please help.

-1</= n </= 2

-2 no
-1 yes
0 yes
1 yes
2 yes
3 no

To write the set in roster form, we need to list all the integers within the given range. In this case, the range is from -1 to 2, inclusive.

The numbers that satisfy the given conditions are -1, 0, 1, and 2. So, we can write the set in roster form as follows:

{-1, 0, 1, 2}

This means that the set "n" consists of the integers -1, 0, 1, and 2.
