Step 1 :
\Thu function
Domain :
\Thu function
The function continuous for all the points except at
.
Thus, the domain of the function is
.
Intercepts :
\y - intercept is :
Thus, y - intercept is .
x - intercept :
\Consider and solve for x.
Thus, x - intercept is .
Step 2 :
\\
Symmetry :
\If , then the function
is even and it is symmetric about x-axis.
If , then the function
is odd and it is symmetric about origin.
Here
Thus, the function is neither even nor odd.
Step 3 :
\Asymptotes :
\Vertical asymptote exist when denominator is zero.
\Equate denominator to zero.
\Vertical asymptote is
Horizontal asymptote:
\The line is called a horizontal asymptote of the curve
if either
or
\
Thus, the horizontal asymptote is
Step 4 :
\Intervals of increase or decrease :
\Differentiate with respect to x:
is never zero.
f is increasing on its domain because
Step 5 :
\Determination of extrema :
\f is an increasing function, hence there is no chance of local minimum or maximum.
\Step 6 :
\Differentiate with respect to x:
Determination of inflection point:
\ is never zero.
Hence, there is no inflection points.
\But at the function is undefined.
Consider the test intervals as and
\
Interval \ | \
Test Value | \Sign of ![]() | \
Concavity | \
![]() | \
![]() | \
\
| \
Up | \
![]() | \
![]() | \
\
| \
\
Down \ | \
Thus, the graph is concave up on the interval .
The graph is concave down on the interval .
