What is the image and preimage of a function and how to write it

The image of a function sounds complicated but it's not as bad as you think.

It's really just the mapping of an element in one set to another element in another set.

The pre-image is then the reverse (or inverse) of that same process - all of this is explained in the video above.

Awesome video! Would 3 also be the pre-imege of C since 1 and 3 both point to C?
