The real valued function

f(x) = \frac{{\mathrm{cose}{\mathrm{c}^{ - 1}}x}}{{\sqrt {x - [x]'} }}

where

\left[ x \right]

denotes the greatest integer less than or equal to

x

, is defined for all

x

belonging to

View answer and explanation

Correct option: B

all non-integers expect the interval [-1, 1]

Option B is correct because the function is defined when |x| >= 1 and x is not an integer, excluding the interval [-1, 1].
