f^-1(x) =1/4 * e^(x/3)
what is the domain of f^-1
Dear mathseek,
domain means all the x value where the function is defined. It's easier usually to search where the function ISN'T defined.
So the questions: What number cann't you divide by 3 or what number cann't you put up as exponent or what number cann't you multiply by (1/4)?
