table value function help

I have a table value function and would like the first and second input to take multiple arguments (array or list) I suppose.  Like the below:

create or replace function myfunction(sector, agency, term)

returns table (cusip char(9), sector char(12))

select foo

from

atable

where

sector in (myfunction.sector)

usage

sectorselect('sector_1 sector_2', 'agent_1 agent_2, 120)
