How to tell the difference between onto and one to one functions

[brianmclogan]

Great point, it our high schools we do not introduce co-domain but it may be something I should look into letting students know about. Thanks

Sir, I mean every word when I say that you have saved me from the trouble of 90+ minutes of lecture in just 4 minutes.

I think you should have "co-domain" in place of "range" since range is a subset of the co-domain where its values all have mappings to the domain. So if my understanding is correct, when you have a co-domain with values in it that don't have a mapping to the domain, it can't be labelled as the range.(correct me if I'm wrong). Other than that, great job. Very clear explanation.
