### Writing Equations from Quadratic Graphs

**Task:** Write an equation (any form) for the quadratic graphed below:

**Graph Details:**
- The graph depicts a quadratic function, showing a parabolic curve opening downwards.
- The vertex of the parabola is at the point (2, 2).
- The parabola intersects the x-axis at approximately (0,0) and (4,0).
- The y-axis ranges from -5 to 5.
- The x-axis ranges from -5 to 5.

**How to Determine the Equation:**
1. **Identify Key Features:**
   - Vertex (h, k): (2, 2)
   - X-intercepts: (0, 0) and (4, 0)

2. **Using Vertex Form of a Quadratic Function:**
   The vertex form of a quadratic equation is given by:
   \[
   y = a(x - h)^2 + k
   \]
   Substituting the vertex (2, 2):
   \[
   y = a(x - 2)^2 + 2
   \]

3. **Determine 'a' Using Another Point:**
   Use one of the x-intercepts, say (0, 0), to find the value of 'a'.
   \[
   0 = a(0 - 2)^2 + 2
   \]
   \[
   0 = 4a + 2
   \]
   \[
   -2 = 4a
   \]
   \[
   a = -\frac{1}{2}
   \]

4. **Write the Final Equation:**
   \[
   y = -\frac{1}{2}(x - 2)^2 + 2
   \]

**Conclusion:**
The equation of the quadratic graph is:
\[
y = -\frac{1}{2}(x - 2)^2 + 2
\]

Please enter the equation in the box provided:
```
y = [     ]
```
