Question

Write the inequality in interval notation
X is greater than or equal to negative 4

Answer 1

Here is our inequality.

`x \geq -4`

Let's go from least to greatest, and add in infinity as our maximum.

`-4 \leq x \ \textless \ \infty`

Our interval notation would look like this.

`[-4,\ \infty)`
We put the lower bound, then the higher bound, using brackets instead of parentheses if x can also be equal to that value.
