Question

[-9,-4] U (-4, 19) Simplify the following Union and/or intersection

Answer 1

The union and intersection of the sets is given as  { -4, -9 , 19} and { -4} respectively.

What is a set?

A set is simply a  mathematical model for a collection of different things which could be elements or members.

Union of sets represented with '∪' is the combination of two sets without repetition

Intersection of sets represented with '∩' is the sum of elements common between the.

From the expression given, we have;

[-9,-4] U (-4, 19)

= { -4, -9 , 19}

[-9,-4] U (-4, 19)

= { -4}

Thus, the union and intersection of the sets is given as  { -4, -9 , 19} and { -4} respectively.
