Question

Write in set builder form : A is set of integers between -15 and +15

Answer 1

Answer:

A = {x : x ∈ Z, -15 < x < 15}

Step-by-step explanation:

A = {x : x ∈ Z, -15 < x < 15}

In set builder form, we use curly braces {} to write the elements of the set or to write the properties which make the set. The symbol ':' means 'such that'. Different properties are separated by a comma ','.

Here, x ∈ Z means x belongs to the set of integers.

Note: Integers between -15 and 15 does not include -15 or 15. Therefore no '=' sign is used.
