![**Problem 4: Solving a Differential Equation**
**Objective:**
The aim is to solve the following differential equation using any appropriate methods to find the general solution. Subsequently, use the provided initial condition to determine the specific solution. Finally, graph the specific solution.
**Given Differential Equation:**
\[ x y y' + 4x^2 + y^2 = 0 \]
**Initial Condition:**
\[ y(2) = -7 \]
\[ x > 0 \]
**Instructions:**
1. **Solve the General Equation:**
Begin by rearranging and solving the given differential equation to obtain a general solution in terms of \( x \) and \( y \).
2. **Find the Specific Solution:**
Utilize the initial condition \( y(2) = -7 \) to determine the specific solution from the general solution derived.
3. **Graph the Specific Solution:**
Once the specific solution is found, plot the graph of \( y \) as a function of \( x \) in the specified domain \( x > 0 \).
**Graph Explanation:** (No graph is provided in the image, but a typical explanation would be—)
- **Axes:** The horizontal axis represents \( x \) and the vertical axis represents \( y \).
- **Curve:** The specific solution will typically be a curve showing the relationship between \( x \) and \( y \).
- **Points:** Particular points of interest, such as the given initial condition \( (2, -7) \), should be highlighted on the graph.
Ensure the graph clearly represents the behavior of the solution over the defined domain \( x > 0 \).](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fac0f3c56-5561-4b47-8ddf-f02546f51c3e%2F2345c547-6bbd-4659-8f2f-a11e1018ef30%2Fvops06r_processed.png&w=3840&q=75)
