No, it is not an f, unless that is how f is defined.
Suppose you wish to differentiate x/f(x) where f(x) is a differentiable function of x, and writing f for f(x) and f'(x) for the derivative of f(x), d/dx (x/f) = [f - x*f']/(f2)
Suppose N is a perfect number. Then N cannot be a square number and so N has an even number of factors.Suppose the factors are f(1) =1, f(2), f(3), ... , f(k-1), f(k)=N.Furthermore f(r) * f(k+1-r) = N for r = 1, 2, ... k so that f(r) = N/f(k+1-r)which implies that 1/f(r) = f(k+1-r)/NThen 1/f(1) + 1/(f(2) + ... + 1/f(k)= f(k)/N + f(k-1)/N + ... + f(1)/N= [f(k) + f(k-1) + ... + f(1)] / N= 2N/N since, by definition, [f(k) + f(k-1) + ... + f(1)] = 2N
A function f(x) is Even, if f(x) = f(-x) Odd, if f(x) = -f(-x)

A source is some type of original material such as diaries or artifacts that gives you information. Evidence is information that is relevant in proving a disputed fact for a legal proceeding.
Ah, the epic sax guy! He plays a catchy combination of notes known as the "D-E-F#" riff. It's a simple yet powerful sequence that brings joy to many listeners. Just like painting, music has its own way of touching our hearts and souls.
