If (f:\mathbb{R}\to\mathbb{R}), (f(x)=\frac{x}{1+|x|}), then (f) is not onto because

Answer and explanation

Correct answer: Its range is ((-1,1))

Step 1: However large (x) is, (\frac{x}{1+|x|}) remains less than (1). In the negative direction, it remains greater than (-1). Step 2: So the range is ((-1,1)), while the codomain is (\mathbb{R}). Step 3: In rational-type functions, limiting values often stay outside the range.
