We'll examine each term of the given function. The mathematical constant e is an irrational number and pi is also a mathematical constant that gives the ratio of a circle to it's diameter.
Being an addition of constant functions, the function f(x) is a constant, therefore the derivative of a constant function is zero.
We'll differentiate the function with respect to x:
f'(x) = 0 + 0
f'(x) = 0
Therefore, the requested derivative of the function is f'(x) = 0.
