Correct Answer

Concept
The open dot excludes (-9) and the right ray takes values greater than it. In exams write (>) as (\(a,\infty\)).
Why this answer is correct
The correct answer is C. (\(-9,\infty\)). The open dot excludes (-9) and the right ray takes values greater than it. In exams write (>) as (\(a,\infty\)).
Exam Tip
खुला बिंदु (-9) को हटाता है और दाईं रेखा उससे बड़े मान लेती है। परीक्षा में (>) को (\(a,\infty\)) के रूप में लिखें।
