| Topic | Curve Sketching |
| Type | Identify transformation from two graphs |
| Difficulty | Moderate -0.8 This is a straightforward transformation identification question requiring visual recognition of standard graph transformations (likely translations and/or reflections). It tests basic understanding of function notation and transformations with no calculation or problem-solving required—purely pattern recognition from given diagrams. |
| Spec | 1.02w Graph transformations: simple transformations of f(x) |
Question 6:
(i) y = 2f(x)
(ii) y = f(x − 3)
**Marking points:**
M1 for y = kf(x), k > 0
M1 for y = f(x + 3) or y = f(x – k)
**Guidance:**
1 if 'y=' omitted [penalise only once]6
