If the number line has open dots at (-10) and (-3), and both outer parts are shaded, what is the interval?यदि संख्या रेखा पर (-10) और (-3) पर खुले बिंदु हैं तथा बाहर के दोनों भाग छायांकित हैं, तो अंतराल क्या है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: ((-\infty,-10)\cup(-3,\infty))((-\infty,-10)\cup(-3,\infty))
Because the endpoints are open, (-10) and (-3) are excluded, and two outer parts are taken. In exams, outer shading means two separate rays.खुले सिरों के कारण (-10) और (-3) शामिल नहीं हैं और बाहर के दो भाग लिए जाते हैं। परीक्षा में बाहर छायांकन का अर्थ दो अलग किरणें होता है।
