Answer:
-4 ≤ y ≤ 2
Explanation:
You want the range of the graph shown.
Range
The range of a relation is the set of output values of the relation, the vertical extent of its graph.
The graph shown extends continuously from an absolute minimum of y=-4 to an absolute maximum of y=2.
The range is -4 ≤ y ≤ 2.
