Write the following set in roster form and in set-builder notation.
P is the set of integers that are greater than -3 and less than or equal to 1
Roster form: P = {-2, -1, 0, 1}
Set-builder notation: P = {x | -3 < x ≤ 1}
Roster form: P = {-2, -1, 0, 1}
Set-builder notation: P = {x ∈ ℤ : -3 < x ≤ 1}
To write a set in roster form, we list all the elements in the set within curly brackets {}. To write it in set-builder notation, we use a description that describes the set's properties.
1) Roster form:
P = {-2, -1, 0, 1}
2) Set-builder notation:
P = {x | -3 < x ≤ 1}
