| Topic | Modulus function |
| Type | Interpret or complete given sketch of two |linear| functions |
| Difficulty | Moderate -0.8 This is a straightforward modulus equation requiring students to consider cases where expressions inside the modulus are positive or negative. Part (a) is trivial coordinate finding (intercepts), and part (b) involves standard case-by-case analysis or squaring both sides—a routine technique covered early in Further Maths with no novel problem-solving required. |
