In the 8th Edition UNIX shell, you simply export them via the environment.
In the BRL SVR2 Bourne shell, you define the functions in the per-
interactive-shell startup file named in the ENV environment variable
(the usual usage around here is to define ENV as ~/.env and have ~/.env
source a ~/.funcs file that contains the definitions).  Note that this
scheme prevents having functions screw up shell scripts (which are not
run as "interactive").
In a vanilla UNIX System V Bourne shell, you cannot obtain the desired
effect so far as I am aware.
