Let `f: R -> B` is given by `f(x)=(2x^8+6x^4+4x^2+3)/(x^8+3x^4+2x^2+1)`. Interval of B for which `f` is onto is

Let f:R rarr B is given by f(x)=(2x^(8)+6x^(4)+4x^(2)+3)/(x^(8)+3x^(4)+2x^(2)+1). Interval of B for which f is onto is

Let f: R to R be defined by f(x) = (3x^(2)+3x-4)/(3-3x + 4x^(2)) , then

Let f : R to and f (x) = (x (x^(4) + 1) (x+1) +x ^(4)+2)/(x^(2) +x+1), then f (x) is :

Let f : R->R be a function defined by f() =(x^2-3x+4)/(x^2+3x+4)then f is (1) one-one but not onto (2) onto but not one -one (3) onto as well as one- one (4) neither onto nor one- one

Let f:R rarr R be a function defined by f(x)=(x^(2)-3x+4)/(x^(2)+3x+4) then fis-
