The function is .
The domain of the function is set of all values at which the function is continuous.
\The denominator should not be equal to .
Therefore the function is undefined at the real zero of the denominator .
The real zeros of is
and
.
Thus, the function is continuous for all real numbers except .
Therefore, Domain .
