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 zero of
is
.
Thus, the function is continuous for all real numbers except
.
Therefore Domain
.
Check for vertical asymptotes :
\Determine whether
is a point of infinite discontinuity.
Find the limit as
approaches
from the left and the right.
