Problem: A transformation of a graph of y = f(x) is represented by the equation y + 6 = -3f[1/3x - 1].
1. Explain the transformations that are occurring in this scenario.
2. Provide the mapping notation for this transformation.
3. If the point (5, -6) lies on graph of y = f(x), then what are the coordinates of the corresponding point on the transformed graph?
4. If the point (2, 6) lies on the transformed graph, then what are the coordinates of the corresponding point on the parent function?
