What is the range of (f(x)=3|x+2|+1)?फलन (f(x)=3|x+2|+1) की रेंज क्या है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: ([1,\infty))([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).(|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।
