If \([x]\) denotes the greatest integer \(\leq x\), then the range of the real valued function \(f(x)=\frac{1}{\sqrt{x-[x]}}\) is

  1. A \([0,1)\)
  2. B \((0,1)\)
  3. C \((1, \infty)\)
  4. D \([1, \infty)\)
Verified Solution

Answer & Solution

Correct Answer

(C) \((1, \infty)\)

Step-by-step Solution

Detailed explanation

We are given that \(f(x)=\frac{1}{\sqrt{x-[x]}}\) but \(\mathrm{x}-[\mathrm{x}] \in(0,1)\) \(\Rightarrow \mathrm{f}(\mathrm{x}) \in(1, \infty)\)
