Given function, f(x) = 1/(x)

Here we have an expression in the denominator.

We know that if there is ‘0’ in the denominator, then the value is undefined.

1/0 = undefined

Hence the domain of the function is any Real number, R except ‘0’.

Here we have a square root expression in the denominator and hence we have 2 limitations:

1/0 = undefined Hence x ≠ 0

‘x’ can be any positive number, but ‘x’ cannot be any negative number.

Hence the domain of function does not include negative numbers and ‘0’.
