Write the value of lim (f(x) - f(c))/(x - c), [x ∈ c]

Question

Write the value of \(\lim\limits_{x \to c}\frac{f(x)-f(c)}{x-c}\)

Answer 1

By definition of derivative we know that derivative of a function at a given real number say c is given by:

∴ as per the definition of derivative of a function at a given real number we can say that –
