Derivative definitionEasyQuestion 360001
Question
The derivative f'(x) is defined as:
- Alim(h→0) [f(x+h)−f(x)]/hCorrect
- Bf(x+h)−f(x)
- C[f(x+1)−f(x)]/1
- Dlim(h→1) [f(x+h)−f(x)]/h
Correct answer
lim(h→0) [f(x+h)−f(x)]/h
Explanation
First principles definition of the derivative: f'(x) = lim(h→0) [f(x+h)−f(x)]/h, provided this limit exists.
