Answer:
![Interval: [-10.10]](https://tex.z-dn.net/?f=Interval%3A%20%5B-10.10%5D)
Step-by-step explanation:
Given
Set: -10 to 10
Required
Write as interval notation
We start by writing the given parameter as an inequality

The direct representation of
and
in interval representation of sets is
and
, which shows that the beginning and end of the interval are inclusive;
So, the above inequality in interval notation is:
![Interval: [-10.10]](https://tex.z-dn.net/?f=Interval%3A%20%5B-10.10%5D)
