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.
