Question
1. **(Section 17.1)** Match the vector fields with their sketches below by placing the letter of the function in the corresponding blank:

\[
\begin{array}{lll}
\text{(I)} & \vec{F}(x, y) = \langle -y, -x \rangle & \\
\text{(II)} & \vec{F}(x, y) = \langle y^2, x \rangle & \\
\text{(III)} & \vec{F}(x, y) = \langle y, -x \rangle & \\
\text{(IV)} & \vec{F}(x, y) = \langle x + y, y - x \rangle & \\
\end{array}
\]

- **Vector Field (A):**  
- **Vector Field (B):**
- **Vector Field (C):**
- **Vector Field (D):**

### Explanation of Vector Field Diagrams

**Vector Field (A):**  
- The arrows form concentric circular patterns around the origin, indicating a spiral or rotational field.

**Vector Field (B):**  
- The arrows are directed outward from the center, suggesting a divergence from the origin.

**Vector Field (C):**  
- The vectors appear to create a clockwise circular motion around the origin, potentially indicative of a curl or vortex.

**Vector Field (D):**  
- The pattern shows arrows converging towards the center, suggesting an inward flow to the origin.
