If the function

\mathrm{f}: \mathrm{R}-\{1,-1\} \rightarrow \mathrm{A}

defined by

f(x)=\frac{x^2}{1-x^2}

, is surjective, then

\mathrm{A}

is equal to:

View answer and explanation

Correct option: C

\mathrm{R}-[-1,0)

Option C (R-[-1,0)) is correct because the range of the function is all real numbers except for the interval [-1, 0).
