फलन (f(x)=3|x+2|+1) की रेंज क्या है?
What is the range of (f(x)=3|x+2|+1)?
Explanation opens after your attempt
A. \([1,\infty\))
Concept
The minimum value of (|x+2|) is (0), so the output is at least (1). In exams the multiplier (3) does not change the minimum when modulus is (0).
Why this answer is correct
The correct answer is A. \([1,\infty\)). The minimum value of (|x+2|) is (0), so the output is at least (1). In exams the multiplier (3) does not change the minimum when modulus is (0).
Exam Tip
(|x+2|) की न्यूनतम वैल्यू (0) है, इसलिए आउटपुट कम से कम (1) होगा। परीक्षा में गुणक (3) न्यूनतम को नहीं बदलता जब मापांक (0) हो।
