| Topic | Function Transformations |
| Type | Identify transformation from equations |
| Difficulty | Easy -1.2 This is a straightforward C1 transformations question requiring only basic recall: (i) identifying a horizontal translation from the standard form, and (ii) sketching a simple parabola with a vertical shift. Both parts are routine textbook exercises with no problem-solving or multi-step reasoning required. |
