I find the bash man page large and complicated, so I can't say for sure how explicitly stated this is.
At line 384sqq of the bash manpage for GNU Bash 4.4, part of section PARAMETERS:
@ Expands to the positional parameters, starting from one.
When the expansion occurs within double quotes, each parameter expands
to a separate word. That is, "$@" is equivalent to "$1" "$2" ... If
the double-quoted expansion
occurs within a word, the expansion of the first
parameter is joined with the beginning part of the original word, and
the expansion of the last parameter is joined with the last part of
the original word. When there are no posi-
tional parameters, "$@" and $@ expand to nothing (i.e.,
they are removed).
