If (f:\mathbb{R}\to(-2,2)), (f(x)=\frac{2x}{1+|x|}), choose the correct option.यदि (f:\mathbb{R}\to(-2,2)), (f(x)=\frac{2x}{1+|x|}) है, तो सही विकल्प चुनिए।
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: It is ontoयह आच्छादी है
Step 1: The range of (\frac{x}{1+|x|}) is ((-1,1)). Step 2: Multiplying by (2) changes the range to ((-2,2)). Step 3: Since the codomain is also ((-2,2)), the function is onto.चरण 1: (\frac{x}{1+|x|}) का परास ((-1,1)) है। चरण 2: (2) से गुणा करने पर परास ((-2,2)) हो जाता है। चरण 3: सहप्रांत भी ((-2,2)) है, इसलिए फलन आच्छादी है।
