| Topic | Function Transformations |
| Type | Multiple separate transformations (sketch-based, standard transformations) |
| Difficulty | Easy -1.8 This is a routine transformation question requiring only recall of standard function transformations (vertical stretch and horizontal stretch). Students need to identify key points and apply simple scaling rules with no problem-solving or conceptual insight required. This is significantly easier than average A-level content. |

The diagram shows the graph of $y = \text{g}(x)$.
In the printed answer booklet, using the same scale as in this diagram, sketch the curves
\begin{enumerate}[label=(\alph*)]
\item $y = \frac{3}{2}\text{g}(x)$, [2]
\item $y = \text{g}\left(\frac{1}{2}x\right)$. [2]
\end{enumerate}
