फलन (f(x)=x-2+4) का परिसर क्या है?
What is the range of (f(x)=x-2+4)?
Explanation opens after your attempt
Correct Answer
A. \([4,\infty\))
Concept
Since \(x^2 \ge 0\), \(x^2+4 \ge 4\). Hence the range is \([4,\infty\)).
Why this answer is correct
The correct answer is A. \([4,\infty\)). Since \(x^2 \ge 0\), \(x^2+4 \ge 4\). Hence the range is \([4,\infty\)).
Exam Tip
क्योंकि \(x^2 \ge 0\), इसलिए \(x^2+4 \ge 4\) है। अतः परिसर \([4,\infty\)) है।
