Question 51259: State the domain and range of f^-1 (x) given
a) f(x)= x+3
This is what I have tried so far:) I found the inverse of the question I think this is right.
y=x+3
x=y+3
x-y=3
-y=3-x
y=x-3
f^-1(x) = x-3 now I know I have to find the domain and range of f^1(x) =x-3 but I am extremely confused on how to do this I know x value is domain and y is range. Can you please help me find the correct answer.

There are no limitations to f^-1(x) = x - 3 , so the answer for the domain is all real values.
