Functions

Question

Consider the following function

$ f(x) = \frac{x} {2x+1} $  $x \ne \frac{-1} {2}$

Which of the flowing is true?

A If f is defined for R → R then f is not one to one.

B If f i defined for R → R then f is not onto

C If f is defined for R → R the f is bijection

Comments

To be bijective, Question should be like this.

A -> R -{  - $\frac{1}{2}$} , B -> R - {$\frac{1}{2}$}

For relation A->B. wheref(x) = $\frac{x}{2x+1}$

Hmm correct

thanks

@kumar.dilip $A\rightarrow R-\left \{ \frac{1}{2}\right \}$ is not required, it would still be bijective
