The function is .

Domain :

The function .

The function is continuous for all the points except at  and .

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 odd and it is symmetric about origin.

Asymptotes :

Vertical asymptote exist when denominator is zero.

Equate denominator to zero.

Vertical asymptotes are at  and .

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  with respect to :

 is never zero on its domain.

 is undefined  when  and .

 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 on its domain.

 is undefined  when  and .

Equate  to zero.

Real solution is .

Inflection point is .

Consider the test intervals as , , and .

\ Interval \	Test Value	Sign of	Concavity
		\ \	Up
		\ \	Down
		\ \	Up
		\ \	\ Down \

Thus, the graph is concave up on the interval  and .

The graph is concave down on the interval  and .
