| Type | Find derivative of simple polynomial (integer powers) |
| Difficulty | Easy -1.3 This is a straightforward differentiation exercise requiring only basic application of the power rule. Both parts are routine calculations with no problem-solving element—students simply apply standard differentiation formulas they've memorized. This is easier than average for A-level, being a foundational C1 skill. |
