Let f: R \to R be a function such that f(x)=\frac{x^2+2 x+1}{x^2+1}. Then [29-Jan-2023 Shift 1]

Correct Answer is : f(x) is one-one in [1,∞) but not in (−∞,∞)

f(x) is many-one in (-\infty,-1)

f(x) is many-one in (1, \infty)

f(x) is one-one in [1, \infty) but not in (-\infty, \infty)

f(x) is one-one in (-\infty, \infty)
