To demonstrate the transformation of shifting a triangle 2 units to the right on a coordinate grid, Suwanda can use the following function:
\[ f(x) = x - 2 \]
This function shifts the x-coordinates of all points in the triangle 2 units to the right. When you take any point (x, y) in the triangle and apply the function, the new point will be (x + 2, y).
However, since the options are not clearly listed, based on the context, the function likely intended is:
\[ f(x) = x - 2 \]
This is because a shift to the right of 2 units modifies the x value by subtracting 2, effectively translating the graph rightward.
