What's the inverse of f(x)=e^(x-11)-8
I got y= ln(x+8)+11
Is this right?
Thanks.
I get the same answer too. Although technically it is written as
Note that the domain of is limited to because we cannot take the log of a negative number or 0 (well we can but then we get complex answers). The range is all the real numbers.
edit (more info): If you look at you may notice that the range is and that the domain is all the real numbers. If you compare that to the range and domain of you will see they've 'swapped' around. This is a property of all inverse functions. Furthermore functions and their inverses are reflections in the line
