| Topic | Function Transformations |
| Type | Describe transformation from graph |
| Difficulty | Moderate -0.8 This is a straightforward C1 question on basic function transformations requiring visual identification of a horizontal or vertical shift and matching to standard notation. It involves minimal calculation and tests only recognition of standard transformation forms, making it easier than average for A-level. |

Fig. 2 shows graphs $A$ and $B$.
\begin{enumerate}[label=(\roman*)]
\item State the transformation which maps graph $A$ onto graph $B$. [2]
\item The equation of graph $A$ is $y = f(x)$.
Which one of the following is the equation of graph $B$?
$y = f(x) + 2$ \quad $y = f(x) - 2$ \quad $y = f(x + 2)$ \quad $y = f(x - 2)$
$y = 2f(x)$ \quad $y = f(x + 3)$ \quad $y = f(x - 3)$ \quad $y = 3f(x)$ [2]
\end{enumerate}
