Question

Help Please. Attachment to follow.

Answer 1

It is asking for the possible values of x and y for the inverse of this function. Remember you cannot divide by zero.

Answer 2

But how do you find the inverse?

Answer 3

hym im not sure on that one. Im guessing it does not effect the domain, but that's strictly a guess.

Answer 4

cause think about what an inverse function is. The domain of an inverse function is the co-domain of the original function and its co-domain is the domain. get it?
