Answer:

See below.

Step-by-step explanation:

The above function could be written as,

{e}^{f(x)}  = e -  {e}^{x}

In the logarithmic form,

 log_{e}(e -  {e}^{x} )  = f(x)

Now, the above function is defined for values of,

e -  {e}^{x}   > 0

On solving,

e >  {e}^{x} \\  log_{e}(e)  >  log_{e}( {e}^{x} )  \\ 1 > x

Hence, the domain of the function is the set of all real numbers smaller than 1.

In a simple form,

range = { x | x = log base=e ( e - e^a ) where 1 > a }
