The domain of the relation is x = - 2 and the range of the relation is -2 ≤ y < 1
What is the range of a relation?
The range of a relation is the possible values of the output of the relation.
What is the domain of a relation?
The domain of a relation is the possible value of the input of the relation.
How to find the range and domain of the relation?
Looking at the graph, we see the only value for x is x = - 2. Since this is the input of the relation.
So, the domain is x = - 2.
Looking at the graph, we see that the minimum value of y is at y = - 2 and its maximum value is at y = 1. Also, we see that the circle at y = - 2 is shaded, so that value of y is included but, the circle at y = 1 is not shaded, so y = 1 is not included.
So, the range is -2 ≤ y < 1
So, the domain of the relation is x = - 2 and the range of the relation is -2 ≤ y < 1
