Consider a function that describes how a particular car’s gas mileage depends on its speed. What would be an appropriate domain
natta225 [31]
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.
