How to call Microsoft SQL User defined function??

Question

I am trying to call Miscrosoft SQL user defined function (not stored procedure) and experience problems. The function -- func_profile_history takes 3 inputs and returns resultSet.
Please let me know if there is any examples some where. All the examples I found are for stored procedure.
Thanks....
