If (f:R\to R), (f(x)=|x+2|), what is its range?यदि (f:R\to R), (f(x)=|x+2|), तो इसका परास क्या होगा?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: ([0,\infty))([0,\infty))
Step 1: An absolute value is never negative. Step 2: At (x=-2), (|x+2|=0). Step 3: Therefore the range is ([0,\infty)).चरण 1: परम मान कभी ऋणात्मक नहीं होता। चरण 2: (x=-2) पर (|x+2|=0) मिलता है। चरण 3: इसलिए परास ([0,\infty)) है।
