Suppose the invertible function φ(x) has the domain (−5,11) and the range (−12,1).

Rom4ik [11]

Answer:

Range of $\phi^{-1}$ is (−5,11).

Step-by-step explanation:

Given the invertible function Ф(x) which has the domain (−5,11) and the range (−12,1).

Invertible function is the function that inverses another function i.e if y=Ф(x) then x=g(y) where g is called the inverse of Ф and denoted by $\phi^{-1}$

Given Ф(x) the function whose domain is (−5,11) and range is (−12,1). Therefore, by definition of invertible function there exist a function g with domain (−12,1) and range (−5,11) which is called the inverse function denoted by $\phi^{-1}$

Hence, Range of $\phi^{-1}$ is (−5,11)
