Question 27(b)
[Maximum number: 3]
Write down the three inequalities that define the region R
Edexcel IGCSE Math A Foundation 2.8.E inequalities defining regions
Practise region-description questions by identifying each boundary line and deciding which side of the line contains the shaded region.
How this is tested
- Write three inequalities that define a shaded region bounded by straight lines.
- Use solid or boundary-line information to decide whether ≤, ≥, is needed.
