If f : A → B is a function defined by f (x) = \frac{x^2-x}{x^2+2x} then, which one of the following is true?

Correct Answer is : A = R - {0 , - 2} , B = R - {1} and f−1 (x) is decreasing function

A = R - {0 , 2} , B = R and f (x) is decreasing function

A = R - {- 2} , B = R - {1} and f^{-1} (x) is decreasing function

A = R - {0 , - 2} , B = R - {1} and f^{-1} (x) is decreasing function

Both f (x) and f^{-1} (x) are increasing functions
