Please help me with domain and range of graphs Part 1

dybincka [34]

Answer:

see the attached for domain
Range: (-∞, 4], [3, ∞), [-3, 1]

Step-by-step explanation:

The domain is the horizontal extent of the graph. When the graph has arrows on the end, it extends to infinity in the indicated direction.

The range is the vertical extent of the graph.

Left Graph

We assume the curve is intended to touch, not cross, the line y=4, so the range is ...

range: (-∞, 4]

Middle Graph

We assume the graph continues along the line y=3 to the right indefinitely. Then this value is the minimum of the range.

range: [3, ∞)

Right Graph

The low point on the graph is at y=-3, and it looks like the graph continues to the right along the line y=1. Then the range is ...

range: [-3, 1]
