| Topic | Function Transformations |
| Type | Forward transformation (single point, multiple transformations) |
| Difficulty | Easy -1.2 This is a straightforward recall question on basic function transformations requiring only direct application of standard rules: vertical stretch multiplies y-coordinate by 3, horizontal stretch by factor 1/4 divides x-coordinate by 4. No problem-solving or conceptual insight needed, just mechanical application of memorized transformation rules. |
| Spec | 1.02w Graph transformations: simple transformations of f(x) |
4 The point $\mathrm { P } ( 6,3 )$ lies on the curve $y = \mathrm { f } ( x )$. State the coordinates of the image of P after the transformation which maps $y = \mathrm { f } ( x )$ onto\\
(i) $y = 3 \mathrm { f } ( x )$,\\
(ii) $y = \mathrm { f } ( 4 x )$.
