Need help only solving part c. Thank you
![**For the differential equation**
\[ \frac{dy}{dx} = \frac{1}{2}(y+2)(y-1)^2 \]
**a. Sketch the direction field where** \(-2 \leq x \leq 2\) **and** \(-2 \leq y \leq 2\). **Place the lineal elements on top of the dots.**
**Fill in this table:**
\[
\begin{array}{c|c}
y & \frac{dy}{dx} \\ \hline
2 & \ldots \\
1 & \ldots \\
0 & \ldots \\
-1 & \ldots \\
-2 & \ldots \\
\end{array}
\]
**Graph Explanation:**
The graph is a grid with orange dots marking points from \((-2, -2)\) to \((2, 2)\). The x-axis ranges from -2 to 2, and the y-axis also ranges from -2 to 2.
**b. Explain the similarity in the lineal elements for each vertical strip.**
The lineal elements within each vertical strip on the direction field exhibit similar slopes at corresponding y-values. This suggests that the slope (or direction of the lineal elements) depends solely on the y-value, as the differential equation is independent of x.
**c. Find the critical points for this DE, draw a one-dimensional phase portrait, and classify each critical point as an attractor, repeller, or semi-stable.**](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fcf87c7e2-8e78-47c4-b022-e63bd8a1598e%2Fa24f72bf-39c4-44ef-9222-80e9f54d73cb%2Fyxent7j_processed.png&w=3840&q=75)
