अंतराल (\(-\infty,-4\)) किस असमानता को दर्शाता है?
Which inequality is represented by the interval (\(-\infty,-4\))?
Explanation opens after your attempt
B. (x<-4)
Concept
The value (-4) is excluded and all smaller values are included so (x<-4). In exams read an interval with \(-\infty\) as a left ray.
Why this answer is correct
The correct answer is B. (x<-4). The value (-4) is excluded and all smaller values are included so (x<-4). In exams read an interval with \(-\infty\) as a left ray.
Exam Tip
(-4) शामिल नहीं है और सभी छोटे मान शामिल हैं इसलिए (x<-4) होगा। परीक्षा में \(-\infty\) वाले अंतराल को बाईं रेखा समझें।
