The function is .
Find the intercept :
\To find the -intercept, substitute
in the function.
The-intercept is
To find the -intercept, substitute
in the function.
The -intercept is
.
Find the relative extrema for the function :
Consider .
Differentiate on each side with respect to .
Quotient rule of derivatives : .
.
Find the critical numbers by equating to
.
.
.
Imaginary roots are not considered.
\There is no critical points.
\Therefore, there is no relative extremum points and the function is decreasing for all values of .
Find the points of inflection :
\The first derivative of is
.
Differentiate on each side with respect to .
Quotient rule of derivatives : .
.
The second derivative of is
.
To find inflection points we make.
.
,
,
.
,
and
.
Imaginary roots are not considered.
\The inflection point occurs at .
If , then
.
Thus, the inflection point is .
Find the asymptotes :
\Vertical asymptote :
\The function is .
Vertical asymptote exist when denominator is zero.
\Equate denominator to zero.
\.
Thus, the vertical asymptotes are and
.
Horizontal asymptote :
\The line is called a horizontal asymptote of the curve
if either
or
.
Thus, the horizontal asymptote is .
Graph :
\Draw a coordiante plane.
\Graph the function .
