Which interval is equivalent to \(x\le 4\)?
Explanation opens after your attempt
B. (\(-\infty,4]\)
Concept
In \(x\le 4\), (4) is included so a square bracket is used at (4). Smaller numbers extend toward \(-\infty\).
Why this answer is correct
The correct answer is B. (\(-\infty,4]\). In \(x\le 4\), (4) is included so a square bracket is used at (4). Smaller numbers extend toward \(-\infty\).
Exam Tip
\(x\le 4\) में (4) शामिल है इसलिए (4) पर वर्ग कोष्ठक आएगा। छोटी संख्याएँ \(-\infty\) की ओर जाती हैं।
