If $f(x)$ is a real function defined on $[-1, 1]$,then the function $g(x) = f(5x + 4)$ is defined on the interval

The range of the function $f(x) = [x] - x$ is

If $[x]^2-5[x]+6=0$,where $[.]$ denotes the greatest integer function,then

If $f(x) = \frac{x^2 - 1}{x^2 + 1}$ for every real number $x$,then the minimum value of $f$ is:

Domain of $f(x) = \frac{x}{1-|x|}$ is

If $A \subseteq Z$ and the function $f: A \rightarrow R$ is defined by $f(x) = \frac{1}{\sqrt{64 - (0.5)^{24 + x - x^2}}}$,then the sum of all absolute values of elements of $A$ is
