![**Title: Equilibrium Solutions and Their Classification**
**Objective:**
Determine and classify equilibrium solutions. Sketch the graph of several solutions.
**Differential Equation:**
\[
\frac{dy}{dx} = y^2 - 8y + 15
\]
**Equilibrium Solutions:**
Find the values of \( y \) for which \(\frac{dy}{dx} = 0\).
**Second Derivative:**
\[
\frac{d^2y}{dx^2} =
\]
**Critical Values:**
| Interval | Testing \# | Sign of \(\frac{dy}{dx}\) | Sign of \(\frac{d^2y}{dx^2}\) | Conclusion |
|----------|------------|--------------------------|------------------------------|------------|

**Graph and Classification of Equilibrium Solutions:**
Diagrams: There is an empty graph section provided for sketching the graph of solutions. It features labeled axes, prepared for plotting \( y \) versus \( x \).
**Instructions:**
- Solve the given differential equation to find \( y \) values where the slope is zero.
- Analyze stability by checking the sign of the first and second derivatives.
- Fill in the table with findings pertinent to each interval.
- Use the graph area to visualize the behavior of solutions and classify them based on the derived conclusions.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F4d410cd6-8fc6-4d13-8ff0-7a43ba3056bc%2Ffade6563-c8e9-4ca5-bd1f-469a1cb5b650%2Fjd82ve_processed.jpeg&w=3840&q=75)
