### Reflection of Quadrilateral ABCD Across the x-axis

In this exercise, you are required to plot the image of quadrilateral \(ABCD\) under a reflection across the \(x\)-axis. The initial quadrilateral \(ABCD\) is displayed on a coordinate plane with points \(A\), \(B\), \(C\), and \(D\) being clearly marked. 

#### Explanation of the Initial Quadrilateral

1. **Quadrilateral ABCD:** 
    - \(A(2, 4)\)
    - \(B(-4, 3)\)
    - \(C(-3, -6)\)
    - \(D(0, -3)\)

2. **Coordinate Plane Description:**
    - The \(x\)-axis runs horizontally, and the \(y\)-axis runs vertically.
    - Both axes are labeled with positive and negative values, and a grid with a scale from -7 to 7 on both axes is provided to assist with plotting coordinates accurately.

#### Reflection Process

When reflecting a point across the \(x\)-axis, the \(x\)-coordinate remains the same, while the \(y\)-coordinate is multiplied by \(-1\).

**Reflection of Points:**
- Point \(A(2, 4)\) reflects to \(A'(2, -4)\)
- Point \(B(-4, 3)\) reflects to \(B'(-4, -3)\)
- Point \(C(-3, -6)\) reflects to \(C'(-3, 6)\)
- Point \(D(0, -3)\) reflects to \(D'(0, 3)\)

#### Graphical Representation

The diagram on the coordinate plane showcases:
1. **Original Quadrilateral \(ABCD\):** 
    - Is displayed in blue.
    - Points \(A\), \(B\), \(C\), and \(D\) plotted at their respective coordinates.

2. **Reflected Quadrilateral \(A'B'C'D'\):**
    - Would be displayed with its points mirrored across the \(x\)-axis.
    - Points \(A'\), \(B'\), \(C'\), and \(D'\) should be plotted at their new reflected coordinates.

With all points plotted:
- The shape and size of the quadrilateral ABCD will remain the same after reflection, but its orientation will be flipped across the \(x\)-
