Let
(a) Determine , the inverse function of f. Show work.
....since , we have
................swap and
................solve for
=>
(b) Determine the domain of f. What is the domain of the inverse function?
domain: exclude value that makes denominator equal to zero
->
so, domain is: { element : }
(c) Determine .
plug in
(d) What is f^ -1 ( ____ ), where the number in the blank is your answer from part (c)?
...........if
