Let f(x)=−2−x2f(x)=−2−x2. Find each of the following:
please see attached image, thank you
![(A) \(\frac{f(5) - f(3)}{5 - 3} =\) [blank]
(B) \(\frac{f(3 + h) - f(3)}{h} =\) [blank]
(C) \(\lim_{{h \to 0}} \frac{f(3 + h) - f(3)}{h} =\) [blank]
### Explanation
- **Equation (A)** represents the average rate of change of the function \(f(x)\) between \(x = 3\) and \(x = 5\). This is a basic slope formula for a secant line.
- **Equation (B)** formulates the difference quotient which is used to approximate the derivative. It measures the rate of change around a point \(x = 3\).
- **Equation (C)** represents the derivative of the function at \(x = 3\). This is calculated by taking the limit as \(h\) approaches zero, which gives the slope of the tangent line at that point.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fb11ca76e-99cc-49cc-ab47-e18e3e84e4f7%2Fad824c7c-e5a7-4a2d-936c-5965d84a16e1%2Finvzq5k_processed.png&w=3840&q=75)
