Write the following set in roster form and in set-builder notation. N is the set of integers that are greater than or equal to -2 and less than or equal to 1.
Write the set in roster form. N = {_}
(Use a comma to separate answers as needed.)
N = {-2, -1, 0, 1}
In roster form, the set N can be written as:
N = {-2, -1, 0, 1}
In set-builder notation, the set N can be written as:
N = {x | -2 ≤ x ≤ 1}
To write the set N in roster form, we need to list all the integers that are greater than or equal to -2 and less than or equal to 1.
The integers in the set N are -2, -1, 0, and 1.
So, the set N in roster form is: N = {-2, -1, 0, 1}.
Now let's write the set N in set-builder notation.
Set-builder notation uses a variable and a condition to describe the set. In this case, we can use the variable "x" to represent the integers in the set N.
The condition can be written as:
"x is an integer, -2 ≤ x ≤ 1"
So, the set N in set-builder notation is: N = {x | x is an integer, -2 ≤ x ≤ 1}
