Minimal cost of circuit implementation

A cheap way to implement this circuit is to use NOR gates. Draw the circuit diagram for the lowest cost implementation using these gates.
f(w,x,y,z) = (w + y) * (x + z)


Solution: w + y with ! inverters and x + z with not inverters to another NOR gate which makes them positive again.
