Class 11 Mathematics Linear Inequalities representation on number line Hard Level 46

संख्या रेखा पर ((-\infty,1]\cap\(-3,\infty\)) का सही निरूपण कौन-सा है?

Which is the correct representation of ((-\infty,1]\cap\(-3,\infty\)) on the number line?

Explanation opens after your attempt
Correct Answer

A. ((-3,1])

Step 1

Concept

The common part of the two intervals is from (-3) to (1), excluding (-3) and including (1). In exams, check endpoint inclusion separately in intersections.

Step 2

Why this answer is correct

The correct answer is A. ((-3,1]). The common part of the two intervals is from (-3) to (1), excluding (-3) and including (1). In exams, check endpoint inclusion separately in intersections.

Step 3

Exam Tip

दोनों intervals का common भाग (-3) से (1) तक है, जिसमें (-3) बाहर और (1) शामिल है। परीक्षा में intersection में endpoint inclusion अलग से जाँचें।
