Question

$f:R\to R,f\left(x\right)=e^{|x|}-e^{-x}$ is many-one into function.

• A. True
• B. False

Answer 1

The correct option is B False

$f\left(x\right)=e^{\left(x\right)}-e^{-x}$

For every $x$, there will be different $f\left(x\right)$

$\therefore$ It is a one - one function

$\therefore False$
