Problem 124 of 7
Compare domain and range for representations cost function C(n) = 10n for n items purchased and distance function D(t) = 60t for t hours traveled.
Using a hint is okay. It just tells the trainer to give you a little more review.

Your answer is equivalent to the expected form.
Walkthrough
Full solution stays hidden until you ask for it.
1. Identify domain and range for each representation.
2. Note restrictions from context, graph endpoints, table inputs, or function family.
3. Compare the input and output sets.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
Assuming every representation has all-real domain and range.
