1. **State the problem:** Reflect trapezoid CDEF over the x-axis. 2. **Vertices of trapezoid CDEF:** C(-6, -6), D(-2, -8), E(6, -4), F(-4, -4). 3. **Reflection rule over the x-axis:** For any point $(x, y)$, its reflection over the x-axis is $(x, -y)$. 4. **Apply the reflection to each vertex:** - $C(-6, -6) \to C'(-6, 6)$ - $D(-2, -8) \to D'(-2, 8)$ - $E(6, -4) \to E'(6, 4)$ - $F(-4, -4) \to F'(-4, 4)$ 5. **Final reflected trapezoid vertices:** $C'(-6, 6), D'(-2, 8), E'(6, 4), F'(-4, 4)$. This completes the reflection of trapezoid CDEF over the x-axis.
