Work not a state function

Why is work done by a system not a state function?

Work done by a system is not a state function because it is dependent on the pathway that a reaction takes (path used to go from initial to final state); whereas for state functions, the values can be determined by the initial and final values for the reaction. Work is dependent on the pressure and volume change of a system, which are things that take the reaction from its initial to final state.

It is because the path taken to the end matters. State functions only need the final and the initial points.
