# How do you express intervals as inequalities such as [3,8)?

Jun 9, 2018

$3 \le n < 8$

#### Explanation:

$\left[3 , 8\right)$

When you have brackets [], that means you include that number.

When you have parentheses (), that means you do NOT include that number.

Let's let a number be $n$.

This means that $n$ is greater than or equal to $3$ and less than $8$.

Therefore, the inequality is:
$3 \le n < 8$

Hope this helps!
