What are the given constraints ?
In interval notation, square brackets indicate that a function can take on that value (or uses a less/greater than or equal to sign). Parenthesis indicate that a function cannot take on that value (or uses a less/greater than sign).
In the case of the given set, both inequality signs are less/greater than or equal to. This indicates to us that we will use brackets in both instances because the set can be equal to -2 and 2.

The ratio in simplest form is 4:1
this is because in 8:2 both 8 and 2 can be divided by 2
so if you do the math:
8/2 = 4
2/2= 1
so then set it up in the order it was originally
= 4:1
