Answer:
-1 ≤ y < 3
Explanation:
Pre-Solving
We are given a graph, and we want to find the range of it. The range is all of the y values where the graph exists.
Notice how there are two end points on the graph - one at (-6, -1) and (7,3). We can notice how one of the points is filled, and the other is not.
This means that (-6, -1) is included on the graph, while (7,3) is not.
Solving
We can notice that the graph is only there between (-6, -1) and (7,3). The graph does not exist below -1 nor above 3.
This means that the graph only exists between -1 and 3.
So, the range is -1 ≤ y < 3. The ≤ means that the -1 is included in the range, while the < means that the 3 is not.
