| Topic | Function Transformations |
| Type | Composite transformation sketch |
| Difficulty | Moderate -0.8 This is a straightforward graph transformations question testing basic recall of horizontal stretch and combined translation. Part (a) requires applying a single horizontal stretch (factor 2), while part (b) combines a horizontal shift right 2 units and vertical shift up 1 unit. These are standard AS-level transformations with no problem-solving or novel insight required, making it easier than average but not trivial since students must correctly apply the transformations to the given graph. |

\item On the diagram in the Printed Answer Booklet, draw the graph of $y = f(\frac{1}{2}x)$. [1]
\item On the diagram in the Printed Answer Booklet, draw the graph of $y = f(x - 2) + 1$. [2]
