SQL Functions & Queries

1. If there is a way to write queries & statements in a Function, does it also mean there is another way to write the queries & statement (such as, writing the query by query & statement by statement method)?
2. If my assumption is correct, then why we need Funtions?
3. Are both ways performing a Single Action without interaction with any User Process?
