The domain of the function `y = sqrt(1 - x^2)/x` has to be determined.

The domain of a function y = f(x) is the set of values that x can take on for which y is real and defined.

`y = sqrt(1 - x^2)/x`

For y to be real `1 - x^2 >= 0` and `x != 0`

=> `1 >= x^2`

=> `1 >= x >= -1`

The domain of the function `[-1, 1]- {0}`
