Question

Write the set of points from −6−6 to 33 but excluding −2−2 and 33 as a union of intervals:

Answer 1

In this question, we have to write the set of points from -6 to 3 but excluding -2 and 3 as a union of intervals .

For union, we use U.

For the points that we have to exclude , we put parenthesis on there side that is ().

Therefore the required interval form is

`[-6,-2)U(-2,3)`

As we see that () are used with -2 and 3 . And that's the required interval form .
