Question

Write the set of real numbers from -10 through 10 in interval notation.

Answer 1

`Interval: [-10.10]`

Explanation:

Given

Set: -10 to 10

Required

Write as interval notation

We start by writing the given parameter as an inequality

`Inequality: -10 \leq x \leq 10`

The direct representation of
`\leq` and
`\geq` 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]`
