If f : R - (-1,1) `to` R is defined by f(x) = `(x)/(x^(2)-1)`, verify whether f is one to one.

If f:R-{-2,2}toR is given by (2x)/(x^(2)-4) verfy whether f is one or not

F : R to R defined by f (x) = (1)/(2x^2 +5) the range of F is

If the function f: R -{1,-1} to A definded by f(x)=(x^(2))/(1-x^(2)) , is surjective, then A is equal to (A) R-{-1} (B) [0,oo) (C) R-[-1,0) (D) R-(-1,0)

If f : R to R is defined by f (x) = |x| -5, then the range of f is ……………

Let f: R to R be defined by f(x)=(x)/(1+x^(2)), x in R. Then, the range of f is (A) [-(1)/(2),(1)/(2)] (B) (-1,1)-{0} (C) R-[-(1)/(2),(1)/(2)] (D) R-[-1,1]
