Answer:
- domain: -∞ < x < ∞, or (-∞, ∞)
- range: 5 ≤ y ≤ 35, or [5, 35]
Step-by-step explanation:
Domain
The domain is the horizontal extent of the graph. Here, there are arrows at the ends of the curve, pointing both directions. We understand that to mean the graph extends to infinity in both directions. Then the domain is "all real numbers".
-∞ < x < ∞
(-∞, ∞)

Range
The range is the vertical extent of the graph. Here the graph extends from a low of 5 °F to a high of 35 °F. The arrows at the end of the graph do not indicate that the portion not shown will have any different range. Hence the range is ...
5 ≤ y ≤ 35
[5, 35]
