index, match, offset is not one Excel function, but 3.
In each case, the answer is Excel help.
Type the function name into help, and it will describe the function, show
the syntax, usually give examples, and often give a "See Also" link to
related functions.

Beyond that, Googling either the web or the archives of these groups will
give you vast amounts of extra info.
