Question

A train travels at 100 miles per hour. An equation can be written that compares the time (t) with the distance (d). Define the domain and range.

a. the domain is time (t) and the range is distance (d).
b. the domain is time (t) and the range is 100.
c. the domain is 100 and the range is time (t).
d. the domain is distance (d) and the range is time (t)

Answer 1

A: The domain is time (t) and the range is distance (d).

Explanation:

Answer 2

The answer would be, A the domain is time and the range is distance.

Explanation:

The train is travelling at 100 miles per hour, thus the equation would be d=100t meaning that the distance equals 100 times the amount of time. Now, that means that the input is the amount of time it's been going, and the input is the domain. if the input is the domain, then the only thing left to be the input (range) is the y value, or, in this case, the d value.
