Question

current skill 1
write the domain as an inequality

Explanation:

Step1: Identify graph's left bound

The graph has a closed dot at $x=-2$, so $x$ can equal $-2$.

Step2: Identify graph's right bound

The graph extends infinitely right (arrow), so $x$ has no upper limit.

Step3: Write domain inequality

Combine bounds to form the inequality.
$x \geq -2$

Answer:

$x \geq -2$
