Example of a function Cont’d
The function of a steering wheel in a car is to steer the car in the desired direction, ex- left, right, and to keep the car from going stray on the road.
Another example can be the accelerator in a motor vehicle, its function is to accelerate the vehicle in a forward/reverse direction. Mechanically the accelerator increases the intake of fuel in the engine, increasing the rate of piston motion and therefore burning the fuel faster and moving the vehicle faster.
