Question 1136169: Suppose the invertible function φ(x) has the domain (−5,11) and the range (−12,1).
What is the range of φ^−1(x)? Answer by ikleyn(52797) (Show Source):
Then the range of the function φ^−1(x) is (-5,11), same as the domain of the function φ(x).
It is so, because you can return to any point of the domain with the function φ^−1(x), first making trip x ----> φ(x).
