Domain vs range vs codomain

Domain: set of inputs accepted by the function ("what x can be")

Range: set of outputs from the given set of inputs

Codomain: ever output possible

Imagine you have a car driving. Each hour it drives 50 kilometers. It's been driving for four hours.

In this scenario, the domain would be each hour it drives. The codomain would be the 50 kilometers it can go every hour. This includes the hours that it hasn't driven yet. And the range is anywhere between 0 and 200.

As dheerajdhobley pointed out, I used Range when I meant Co-Domain.

When I originally posted the post I am referring to, I decided on the incorrect Range because I was afraid that too many big words that people are not wont to see would be scary. In addition, seeing “Domain and Range” together I assumed would help contextualize the ideas for more people. I was thinking that people might not make connections to ideas they might already know if I used the correct “Domain and Co-Domain.”

I might edit it to say “the Co-Domain (the subset of the Co-Domain covered by the relation is called the Range).” Trying to decide if this is a happy medium.
