Is a linear transformation one to one? Onto? An isomorphism?

You are an excellent teacher. Thank you for this!

Thanks for this! After watching this video yesterday I found a contradiction in one of the solutions to a previous linear algebra exam at my university…so I brought it up in class and found out that the exam solution was indeed incorrect. So again, thanks for video! 😁👍

Injective is dual to surjective synthesizes bijective or isomorphism! "Always two there are" -- Yoda.
