ANSWER
Domain: [-2, 1]
Range: [-3, -2]
EXPLANATION
We want to find the domain and the range for the relation given in the graph.
The domain of a relation is the set of all input values for the relation, that is the set of all x values.
From the graph, the domain starts from the lowest x value to the highest x value.
That is:
Domain: [-2, 1]
The range of a relation is the set of all output values for the relation, that is the set of all y values.
From the graph, the range starts from the lowest y value to the highest y value.
That is:
Range: [-3, -2]
