| Topic | Function Transformations |
| Type | Identify transformation from equations |
| Difficulty | Easy -1.2 This is a straightforward transformation question requiring recognition that y = 3x^2 + 15 = 3(x^2 + 5), indicating a vertical stretch by scale factor 3. It's a 2-mark question testing basic understanding of function transformations with minimal steps and no problem-solving required—easier than average A-level content. |
| Spec | 1.02w Graph transformations: simple transformations of f(x) |
State the transformation which maps the graph of $y = x^2 + 5$ onto the graph of $y = 3x^2 + 15$. [2]
