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

Find f(-3) given that f(x)=2x(x^2-8x+4)-3x^2-2

If f : R to R is defined by f(x) = x^(2)- 6x + 4 then , f(3x + 4) =

If f: R to R is defined by f(x) = 2x+|x| , then f(3x) -f(-x)-4x=

Let f(x)=(x-2)(x^(4)-4x^(3)+6x^(2)-4x+1) then value of local minimum of f 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

f:R->R is defined as f(x)=2x+|x| then f(3x)-f(-x)-4x=

f:R->R is defined as f(x)=2x+|x| then f(3x)-f(-x)-4x=
