`(x^3+x+1)/(x^2-1)`

The number of integral values which can be taken by the expression, f (x) = (x ^(3)-1)/((x-1) (x ^(2) -x+1)) for x in R, is:

The number of integral values which can be taken by the expression, f (x) = (x ^(3)-1)/((x-1) (x ^(2) -x+1)) for x in R, is: 1 2 3 infinite

For all real values of x if |(x^(2)-3x-1)/(x^(2)+x+1)|<3 limit of x are

int(x(x^(3)+x+1))/(3x^(2)+1)dx

If f(x) {:(=(x^(2)-4x+3)/(x^(2)-1)", ..."x!=1 ),( =2", ..."x=1):} then :

Range of the function f(x)=(x^(2)+3x+1)/(x^(2)+x+1)

int_(-1)^(1) (x^3 + |x| + 1)/(x^2 + 2|x| + 1) dx is equal to :
