Could someone help me with this?

I need to write down 4 REAL LIFE examples of the following derivative rules:

TTHIS IS ONE EXAMPLE SO YOU UNDERSTAND WHAT I NEED

The constant rule says, in Lebesgue's, apostrophy ', notation, that f(x)=c has derivative f'(x)=0.

And here is the example given to this case: f(x)=32 (in physics, the gravity acceleration on earth surface in ft/sq sec) has derivative f(x)=0

(32 is an example of a constant).

Here is what i need 4 examples for:

1. Derivative of a constant: the derivative of a constant is zero.
2. Power Rule: The derivative of a power X^Awith a fixed exponent A, with respect to the base X, is the power A multiplied by the same function except for the exponent lowered by one unit: AX^A-1
3. Constant multiple rule: the derivative of a constant times a function is the constant times the derivative of the function.
4. sum/difference rule: the derivative of the sum ( respectively, difference) of functions is the sum (resp, difference) of the derivatives.
