Question

definition of a first derivative of a function f of x​

Answer 1

Answer: The first order derivative of a function f(x) at x=a is defined as: f '(a)= lim h → 0 f ( a + h ) – f ( a ) h \frac{f(a+h) – f(a)}{h} hf(a+h)–f(a) Another definition is: The derivative of the function f(x) at x=a is defined as: f '(a)= lim x→a f ( x ) – f ( a ) x − a \frac{f(x) – f(a)}{x-a} x−af(x)–f(a)
