| Topic | Function Transformations |
| Type | Multiple separate transformations (sketch-based, standard transformations) |
| Difficulty | Moderate -0.8 This is a straightforward function transformation question requiring only recall of standard transformations (vertical stretch and reflection in x-axis) and application to turning points. The transformations are basic C1 content with no problem-solving or novel insight required—simpler than average A-level questions. |

The diagram shows a sketch of the curve with equation $y = f(x)$. The curve has a maximum at $(-3, 4)$ and a minimum at $(1, -2)$.
Showing the coordinates of any turning points, sketch on separate diagrams the curves with equations
\begin{enumerate}[label=(\roman*)]
\item $y = 2f(x)$, [3]
\item $y = -f(x)$. [3]
\end{enumerate}
