Answer:
Hi!
I will use JAVA to answer the question.
The class AirConditioner could be:
public class AirConditioner {
bolean state;
AirConditioner(){ <em>//constructor</em>
this.state = false;
}
public void turnOff{ <em>//turn off method</em>
this.state = false;
}
public void turnOn{ <em>//turn on method</em>
this.state = true;
}
}
Program to solve the problem:
public static void main(){ <em>//main program</em>
AirConditioner myAC = new AirConditioner(); <em>//instanciate the AirConditioner object</em>
myAC.turnOn(); <em>//call the method turnOn for myAC instance.</em>
}

For any relation R, attribute Y is functionally dependent on attribute X (usually the PK), if for every valid instance of X, that value of X uniquely determines the value of Y.
