Answer:
(d) Domain: x∈ℝ and range: y∈ℝ
Explanation:
You want the domain and range of the relation shown in the graph.
Graph
The graph shows a line. The arrows on the end of it mean that it extends to infinity in both directions (up and left; down and right).
Domain
The domain is the horizontal extent. It includes all real numbers (from -∞ to +∞).
Range
The range is the vertical extent. It includes all real numbers (from -∞ to +∞).
