Answer:
D: 3 ≤ x ≤ 11
Explanation:
Pre-Solving
We are given a graph, where we want to find the domain of it. The domain is the set of all x values where the graph exists.
Solving
If we look at the graph, we can see that the graph has two end points - one at (-2, 3) and the other at (11, 7). We can see that both points are filled, meaning both are included on the graph.
We can see that the graph's x values are between 3 and 11, and there aren't any other parts of the function on the graph past 11 or before 3.
This means the graph only exists where x = 3 and x = 11.
So, the domain is 3 ≤ x ≤ 11.
