When you define a function f ( x) on its domain X, it means that for each x 0 ∈ X you know the value f ( x 0). In a similar sense, the derivative of a function f ( x) in X (if it's differentiable in X) is defined as f ′ ( a) for each a ∈ X, hence f ′ ( a) is a constant, but f ′ ( x) is a function on X.
