Given that {f}: {S} \\to{R} is said to have a fixed point at {c} of {S} if {f}({c})={c}. Let f:[1, \infty) \\toR be defined by f(x)=1+\\sqrt{x}. Then

Correct Answer is : f has unique fixed point in [1,∞)

{f} has no fixed point in [1, \infty)

{f} has unique fixed point in [1, \infty)

{f} has two fixed points in [1, \infty)

{f} has infinitely many fixed points in [1, \infty)
