Question

1. find the domain of the following graph:

Explanation:

Step1: Identify leftmost x-value

The graph starts at $x=-7$ (closed dot, included).

Step2: Identify rightmost x-value

The graph ends at $x=5$ (closed dot, included).

Step3: Define domain interval

Domain is all x-values between the two points, so $-7 \leq x \leq 5$, written as $[-7, 5]$.

Answer:

$[-7, 5]$
