You need to declare the return type of your function:

SQL

create function Age(@date datetime)
RETURNS VARCHAR(12)
as

you need to improve your query.
change your return statement like returns [datatype]

i changed it

SQL

create function Age(@date datetime)
returns datetime-- your problem was here
as
begin
DECLARE @tmpdate datetime, @years int, @months int, @days int, @age varchar(12)
--  declare @date datetime
--   set    @date='12/29/04'
SELECT @tmpdate = @date
SELECT @years = DATEDIFF(yy, @tmpdate, GETDATE()) -
CASE WHEN (MONTH(@date) > MONTH(GETDATE())) OR (MONTH(@date) = MONTH(GETDATE()) AND DAY(@date) > DAY(GETDATE())) THEN 1 ELSE 0 END

SELECT @tmpdate = DATEADD(yy, @years, @tmpdate)

SELECT @months = DATEDIFF(m, @tmpdate, GETDATE()) -
CASE WHEN DAY(@date) > DAY(GETDATE()) THEN 1 ELSE 0 END

SELECT @tmpdate = DATEADD(m, @months, @tmpdate)
SELECT @days = DATEDIFF(d, @tmpdate, GETDATE())
set @age= Convert(varchar(12),(cast (@years as varchar(2)) + '-'+ cast(@months as varchar(2))+'-'+ cast(@days as varchar(4))),11)
--  select @age
return @age
end
