Need help again! Appreciate it! What is the domain? What is the range?
1 answer:
Answer:
- domain: (a) (-∞, ∞)
- range: (b) (-∞, 4]
Step-by-step explanation:
The domain is the horizontal extent of the graph. The arrows on the ends of the lines mean the graph extends indefinitely horizontally in both directions.
The range is the vertical extent of the graph. The arrows on the ends of the lines mean the graph extends indefinitely downward. The upward extent is marked by the turning points at y=4.
<h3>Domain</h3>The horizontal extent of the graph is from negative infinity to positive infinity. Written in interval notation, this is ...
(-∞, ∞)
<h3>Range</h3>The vertical extent of the graph is from negative infinity to +4. Written in interval notation, this is ...
(-∞, 4]
