Which inequality is represented by the interval ((-\infty,-4))?अंतराल ((-\infty,-4)) किस असमानता को दर्शाता है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: (x<-4)(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.(-4) शामिल नहीं है और सभी छोटे मान शामिल हैं इसलिए (x<-4) होगा। परीक्षा में (-\infty) वाले अंतराल को बाईं रेखा समझें।
