WebThe instantaneous rate of change of a function with respect to the dependent variable is called derivative. Let ‘f’ be a given function of one variable and let Δ x denote a number … WebSince f is differentiable over I, f must be continuous over I. Suppose f(x) is not constant for all x in I. Then there exist a, b ∈ I, where a ≠ b and f(a) ≠ f(b). Choose the notation so that a < b. Therefore, f(b) − f(a) b − a ≠ 0. Since f is a differentiable function, by the Mean Value Theorem, there exists c ∈ (a, b) such that
