| Topic | Curve Sketching |
| Type | Single transformation sketches |
| Difficulty | Easy -1.2 This is a straightforward C1 transformation question requiring only basic recall: sketching a vertical stretch (multiply y-coordinates by 2) and describing a horizontal translation. Both are standard textbook exercises with no problem-solving or novel insight required, making it easier than average. |

The graph of $y = \mathrm { f } ( x )$ for $- 2 \leqslant x \leqslant 4$ is shown above.\\
(i) Sketch the graph of $y = 2 \mathrm { f } ( x )$ for $- 2 \leqslant x \leqslant 4$ on the axes provided.\\
(ii) Describe the transformation which transforms the graph of $y = \mathrm { f } ( x )$ to the graph of $y = \mathrm { f } ( x - 1 )$.
