The purpose of the petition sent to King George III by the First Continental Congress was to declare their right to approve laws passed by Parliament on behalf of the colonies.

Explanation:

The Olive Branch Petition, written on July 5, 1775, was a letter sent to King George III of England by the Second Continental Congress during the American Revolution. First written by Thomas Jefferson, it was revised and corrected in a less radical sense by John Dickinson. The petition claimed that the Americans did not want independence, but humbly called for a negotiation about trade and taxes with London.

The letter arrived in London in August and was ignored by George III, who proclaimed the colonies in a state of rebellion. In October, he accused the settlements of aiming for independence, contrary to what was written in petition.

congress also has implied powers, which derive from the necessary and proper clause of the constitution and permit congress "to make all laws which shall be necessary and proper for carrying into execution the foregoing powers, and all other powers vested by this constitution in the government of the united states.
