The equation is .
The function is .
Consider the function is .
Domain :
\The function is .
The function consists radical term, therefore it is defined for .
Since -term is i the denominator part,then it should not equal to zero.
Thus, the domain of the function is all positive numbers.
Intercepts :
\ - intercept is
:
Thus, there is no - intercept.
- intercept :
Consider and solve for
.
Thus, there is no - intercept.
Symmetry :
\If , then the function
is even and it is symmetric about
- axis.
If , then the function
is odd and it is symmetric about origin.
.
Above function is not defined in the domain of the function.
\Therefore, the function is neither even nor odd function.
\Asymptotes :
\Vertical asymptote :
\Vertical asymptote exist when denominator is zero.
\Equate denominator to zero.
\Thus, the vertical asymptote is .
Horizontal asymptote:
\The line is called a horizontal asymptote of the curve
if either
or
Thus, the horizontal asymptote is .
Intervals of increase or decrease :
\Differentiate on each side with respect to .
.
Find the critical points by equating to zero.
Since is not in the domain of the function and therefore there are no critical point.
Thus, the function has no extrema.
