Concept
The interval (\(-\infty,0]\) includes (0) and all smaller values. In exams remember (\(-\infty,0]\) as \(x\le 0\).
Why this answer is correct
The correct answer is B. (0) पर बंद बिंदु और बाईं ओर रेखा / Closed dot at (0) and ray left. The interval (\(-\infty,0]\) includes (0) and all smaller values. In exams remember (\(-\infty,0]\) as \(x\le 0\).
Exam Tip
(\(-\infty,0]\) में (0) शामिल है और उससे छोटे मान शामिल हैं। परीक्षा में (\(-\infty,0]\) को \(x\le 0\) से जोड़कर याद रखें।
