Hi guys I was wondering if someone could give me a little cheat sheet for my quiz tomorrow to help pick up on relations. Can't seem to find my discrete mathematics book
This is what I need to know:
Define a relation R from {...} to {...} by R = {(..., ...), (..., ...), (..., ...), (..., ...)}.
The source of R
The Domain of R
The target or co-domain of R is
The range of R is
The inverse of R is
A website link would be fine that explains these nicely. Greatly appreciate any help.
