B The domain is the set of all real numbers greater than-4.
- Incorrect, the domain can get any value
C The range is the set of all real numbers greater than 0.
- Correct, the range is restricted to positive values
D The domain is the set of all real numbers less than-4.

I am not sure about the formula but if you subtract 8,884 from 10,712 you get 1,828. Then, if you divide that by 4 you get 457. 457 fph(feet per hour) should be the climbers vertical speed.
Answer:
