TopicAreas by integration
TypeArea under polynomial curve
DifficultyModerate -0.8 This is a straightforward area calculation requiring students to form a quadratic from given roots, integrate it between the roots, and take the absolute value. It's a standard textbook exercise with clear boundaries and no conceptual challenges beyond basic integration technique, making it easier than average for A-level.
Spec1.08e Area between curve and x-axis: using definite integrals

8 In this question you must show detailed reasoning. Fig. 8 shows the graph of a quadratic function. The graph crosses the axes at the points \(( - 1,0 ) , ( 0 , - 4 )\) and \(( 2,0 )\). \begin{figure}[h]

\end{figure} Find the area of the finite region bounded by the curve and the \(x\)-axis.

I don't see any actual mark scheme content to clean up in your message. You've provided a question header ("Question 8") and page continuation notes, but no marking points, criteria, or guidance.
Please provide the actual mark scheme content you'd like me to clean up, including:
- Marking annotations (M1, A1, B1, etc.)
- Marking criteria and guidance
- Any mathematical expressions using unicode symbols
Once you share that content, I'll format it with unicode-to-LaTeX conversions and clear formatting.
