The function is .

Domain :

The function .

The function is continuous for all the points except at .

Thus the domain of the function is .

Intercepts :

Find the -intercept by substituting .

Thus, -intercept is .

Find the -intercept by substituting .

Thus, -intercept is .

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.

Here 

Thus, the function  is neither even nor odd.

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  .

Intervals of increase or decrease :

Thu function is .

Differentiate  with respect to .

 is never zero on its domain.

 is increasing on its domain because 

Determination of extrema :

 is an increasing function, hence there is no chance of local minimum or maximum.

Determination of inflection point:

.

Differentiate  with respect to :

 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 .

Graph of the function  :

Graph of the function is
