| Topic | Curve Sketching |
| Type | Sketch two translations on separate diagrams |
| Difficulty | Easy -1.3 This is a straightforward transformation question requiring only basic recall of vertical and horizontal translations. Students simply shift the given graph up 3 units and left 2 units respectively—no calculation, problem-solving, or conceptual insight needed beyond memorizing standard transformation rules. |
