What is (\(-\infty,5\)\cap[5,\infty)) on the number line?
Explanation opens after your attempt
C. \(\emptyset\)
Concept
The first part excludes (5), and the second starts at (5), so there is no common point. In exams, decide intersection only after checking endpoint inclusion.
Why this answer is correct
The correct answer is C. \(\emptyset\). The first part excludes (5), and the second starts at (5), so there is no common point. In exams, decide intersection only after checking endpoint inclusion.
Exam Tip
पहला भाग (5) को शामिल नहीं करता और दूसरा (5) से शुरू होता है, इसलिए कोई common point नहीं है। परीक्षा में endpoint inclusion देखकर ही intersection तय करें।
