Domain are x values (independent variable);
Speed would be independent so what speeds can be used ? -30 mph, 30 mph, 1000 mph?
Can a car go 0 mph?
What is realistic?
I would say 0 greater or equal to x greater than whatever you think is beyond the max that a car can go.
The question doesn't seem to be written correctly, I'm not able to make much sense of it.
Taylor had 15 dollars and Keara gave her 3 More. How much does she have now?
