1. The user asks which questions are important for exams from a list of algebra and functions problems. 2. Since importance varies by curriculum and exam board, I cannot definitively say which questions will appear. 3. However, common exam topics often include: - Expressing coordinates in terms of slope (Q12) - Writing distance as a function (Q13, Q14) - Finding domain and range of functions (Q15-22) - Understanding why certain equations are not functions (Q23, Q24) 4. These topics are fundamental and frequently tested. 5. I recommend focusing on Q12, Q13, Q14, Q15-22, and Q23-24 for exam preparation. 6. Practice problems involving function domains, ranges, distance formulas, and function definitions are essential. 7. Consult your specific syllabus or past papers for precise important questions.
