What a lost mark actually looks like

This answer reaches the right coordinates and still drops a mark. The question asks you to justify — and R marks pay for the reasoning, not the conclusion.

R1 — withheld
The question says "justifying your answer", and R marks are awarded for the reasoning itself — not for the conclusion. Naming which point is the maximum earns nothing on its own. Evaluate f″ $(x) = 6x$ − 6 at each point (−6 at $x = 0$ , +6 at $x = 2$ ), or show the sign of f′ either side. Two lines of working convert this mark.
