| Topic | Function Transformations |
| Type | Multiple separate transformations (sketch-based, standard transformations) |
| Difficulty | Easy -1.2 This is a straightforward recall question testing basic knowledge of function transformations. Students only need to state that (i) is a vertical stretch scale factor 2 and (ii) is a horizontal stretch scale factor 1/2, requiring minimal working and no problem-solving or integration of concepts. |
