Final answer:
The equation of the transformation shown in the dashed orange graph is y=(x-2)^2.
Step-by-step explanation:
The parent function y=x2 is a quadratic function that opens upward and has its vertex at the origin (0,0). The transformation shown in the dashed orange graph is a horizontal shift to the right by 2 units.
When the graph is shifted to the right by 2 units, the equation becomes y=(x-2)2. This is because the positive value inside the parentheses represents the amount of the horizontal shift.
Therefore, the correct equation of the transformation shown in the dashed orange graph is y=(x-2)2 (option a).
