Question
![**Understanding Derivatives: Key Concepts in Calculus**
**Question:** Which is used to compute the derivative of a function? *
1. **Option 1:**
- Formula:
\[
\lim_{{h \to 0}} \frac{{f(x+h) - f(x)}}{h}
\]
- **Explanation:** This represents the definition of the derivative, illustrating the limit process to determine the slope of the tangent line at any point on the function.
2. **f'(x) = 0**
- **Explanation:** This equation implies that the derivative of the function is zero, indicating a horizontal tangent line or a potential local maximum or minimum.
3. **Option 3:**
- Formula:
\[
f'(x) = nX^{n-1}
\]
- **Explanation:** This denotes the power rule in differentiation, used to find the derivative of functions of the form \(x^n\).
4. **All of these**
- **Explanation:** This option considers whether all previous options are applicable in computing derivatives under different contexts or interpretations.
**Choose the correct option that directly applies to differentiating a function.**](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F2685c90a-b1ba-41d6-b583-ded3ee98b219%2Ff784896f-7c4f-448f-b22f-afa21e81bc0e%2F70rabs_processed.jpeg&w=3840&q=75)
