Question

7. The domain of the function f(x) =
[x] = cos^-1 x / (x) is
(a) [-1, 0) {1}
(b) (-1, 1]
(c) (-1, 1)
(d) none of these​

Answer 1

$\huge{\boxed{\overline{\underline{\mathfrak{\fcolorbox{cyan}{blue}{Answer}}}}}}$

=> [-1,0) {1}

f(x) = cos^-1 x / (x)

This function is defined if -1 < x < 1

But. (x) don't = 0

=> (x) E (0,1)

Domain of f(x) = [-1,0) {1}
