1. The problem is to find the minimum value of the parabola shown in the graph. 2. The parabola is U-shaped and opens upward, which means it has a minimum point at its vertex. 3. The vertex is given approximately at the point $(0, -2)$. 4. The minimum value of the parabola is the $y$-coordinate of the vertex because the parabola opens upward. 5. Therefore, the minimum value is $-2$. 6. Using a ruler to draw a horizontal line across the vertex visually confirms that this is the lowest point on the graph. Final answer: The minimum value of the parabola is $-2$.
