Welcome. Functions are expressions, and, in general, can be used just
like constants and column names in the select list, where clause, group
by, and order by. Keep in mind that functions can also be nested (i.e.
the return value of some function can be used as a parameter to
another).

C'mon...even a newbie can figure that out with a little bit of thinking
:) Change the 'F%' to 'A%'. The % is a wildcard that matches 0 or
more characters.

Instead of using the pattern 'F%' (an 'F' followed by zero or more
characters) use '[A-I]%' (a single character in the range A-I followed
by zero or more characters).
