f(x) =2x

x-5

I need to determine the domain and range for f(x). I know that the domain is not equal to 5, but I'm not sure on how to find the range. I think it is all real numbers.

From this one problem, I have to also find the inverse. I came up with:

f(x) =-25x-2

10

But I don't think it is right.

Any help would be great thanks!
