Answer:
The domain is t ≥ 0
The range is D ≥ 0
Step-by-step explanation:
[tex]rate = \frac{distance}{time}[/tex]
D(t) = 100t + d₀
t is the time measured in hours.
d₀ is the initial position of the train.
We can assume the distance they go is not negative so...
The domain is t ≥ 0
The range is D ≥ 0
