Vedclass · Answer

(C) The expression $x-[x]$ represents the fractional part of $x$, denoted as $\{x\}$.Since $x$ is a real number, the fractional part $\{x\}$ lies in the interval $[0, 1)$.However, the denominator $\sqrt{x-[x]}$ cannot be zero, so $x-[x] 
eq 0$.Therefore, $x-[x] \in (0, 1)$.As $x-[x]$ approaches $0$ from the right, $\frac{1}{\sqrt{x-[x]}}$ approaches $\infty$.As $x-[x]$ approaches $1$ from the left, $\frac{1}{\sqrt{x-[x]}}$ approaches $1$.Thus, the range of $f(x)$ is $(1, \infty)$.

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