Easy -1.8 This is a straightforward recognition question testing basic graph transformations. Students only need to identify that a horizontal stretch/compression has occurred by comparing the two graphs, then select from given options. It requires minimal calculation or reasoning—just recall of transformation rules and visual comparison. Worth only 1 mark and significantly easier than typical A-level questions.
The graph of \(y = f(x)\) is shown in Figure 1.

\(y = f(2x)\) \quad\quad \(y = f\left(\frac{x}{2}\right)\) \quad\quad \(y = 2f(x)\) \quad\quad \(y = \frac{1}{2}f(x)\)
