| Topic | Curve Sketching |
| Type | Sketch two translations on separate diagrams |
| Difficulty | Moderate -0.8 This is a straightforward transformation question requiring only basic recall of vertical and horizontal translations. Students need to shift the given curve down 2 units and right 3 units respectively—standard C1 content with no problem-solving or conceptual challenge beyond direct application of memorized rules. |
| Spec | 1.02w Graph transformations: simple transformations of f(x) |
