When expressing sets, you may write "inf" for infinity and "u" for union.
write the complement of the given set in interval notation: (−5,6]

The complement of the given set in interval notation is. It can we written as (-inf,5]U(6,inf).

Step-by-step explanation:

The given set in interval notation is

(−5,6]

It means the set is defined as

If B is a set and U is a universal set, then complement of set B contains the elements of universal set but not the elements of set B.

Here, universal set is R, the set set of all real numbers.

The complement of the given set is

Complement of the given set in interval notation is

Therefore the complement of the given set in interval notation is. It can we written as (-inf,5]U(6,inf).
