यदि (x) वास्तविक संख्या है और \(x\notin[-4,2\)), तो संख्या रेखा पर सही अंतराल कौन सा है?

If (x) is a real number and \(x\notin[-4,2\)), which interval is correct on the number line?

Explanation opens after your attempt
Correct Answer

B. (\(-\infty,-4\)\cup[2,\infty))

Step 1

Concept

The original interval includes (-4) but excludes (2). In the complement, (-4) is excluded and (2) is included.

Step 2

Why this answer is correct

The correct answer is B. (\(-\infty,-4\)\cup[2,\infty)). The original interval includes (-4) but excludes (2). In the complement, (-4) is excluded and (2) is included.

Step 3

Exam Tip

मूल अंतराल में (-4) शामिल है लेकिन (2) शामिल नहीं है। पूरक में (-4) बाहर और (2) शामिल होगा।
