Answer:
B
Domain: (-∞,∞)
Range: (-∞,5]
Step-by-step explanation:
The domain is (-∞,∞) because the graph as you can see, is continuously going outwards forever.
The range is (-∞,5] because the graph as you can see, is always going down forever and the top point is at 5. The 5 is in a bracket because it is a defined number while ∞ is undefined!
Hope this helped and good luck :)
