The equation that best represents the graph shown is y=(x-2)²-3.
To determine this, let's analyze the graph and the transformations necessary to produce it:
1. The graph is a parabola. This suggests that the equation will contain a squared term.
2. The vertex of the parabola appears to be at (2, -3). This means that the equation will involve a transformation that shifts the vertex.
3. The vertex of the original parabola is at (0, 0). Shifting the vertex to (2, -3) involves a horizontal shift of +2 units to the right (subtracting 2 from x) and a vertical shift of -3 units downward (subtracting 3 from y).
4. Putting it all together, we can see that the equation needs to have the form y = (x-2)² - 3.
Therefore, the equation y=(x-2)²-3 best represents the graph shown.
