| Topic | Function Transformations |
| Type | Multiple separate transformations (sketch-based, standard transformations) |
| Difficulty | Easy -1.2 This is a straightforward recall question testing basic knowledge of function transformations. Students only need to state that (i) is a horizontal translation 2 units right and (ii) is a vertical stretch scale factor 3 - no calculation, problem-solving, or application required. Well below average difficulty for A-level. |
| Spec | 1.02w Graph transformations: simple transformations of f(x) |
Question 12:
(i) graph along $y = 2$ with V at $(3,2)$ $(4,1)$ & $(5,2)$
(ii) graph along $y = 6$ with V at $(1,6)$ $(2,3)$ & $(3,6)$
M1 for correct V, or for $f(x+2)$
B1 for $(2,k)$ with all other elements correct(i) $y = \mathrm { f } ( x - 2 )$,\\
(ii) $y = 3 \mathrm { f } ( x )$.
