Question
![**Approximate a Zero Using Newton's Method**
Objective: To approximate a zero of the function \( f(x) = x \cos \sqrt{x} \) on the interval (1, 5) using Newton's method.
**Newton's Method Formula:**
\[ x_{n+1} = x_n - \frac{f(x_n)}{f'(x_n)} \]
Procedure:
1. Choose an initial value \( x_0 \) from the interval (1, 5).
2. Use the formula to calculate the subsequent approximation \( x_2 \).
**Graph Explanation:**
The graph provided displays the function \( f(x) = x \cos \sqrt{x} \) over the interval (1, 5). The curve starts slightly above the x-axis, showing positive values, and then descends, crossing the x-axis indicating potential zeros before it continues to decrease further into negative values.
- **x-axis:** Represents the domain from approximately 1 to 6.
- **y-axis:** Represents the range of function values from roughly -2.5 to 2.5.
- The curve crosses the x-axis between 1 and 5, suggesting possible points to begin the iteration for finding a zero using Newton's method.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fd1296bd5-8576-4c4a-a68a-ae374446bba9%2Fa69200c4-06bd-4b9a-a024-3a2eb7cfbff3%2Fu8rnymr_processed.jpeg&w=3840&q=75)
