The domain of a one-to-one functionf is [0,∞), and its range is[5,∞). State the domain and the range of f-1.

Short Answer

Expert verified

If a function fis one to one function and its domain [0,∞)is and range is [5,∞),then the domain of its inverse function will be[5,∞) and range will [0,∞)

Step by step solution

01

Step 1. Given data  

Function f is one to one function

The domain of function f is[0,∞)

The range of function f is[5,∞)

02

Step 2. The domain of the inverse function

If a function fis one to one function

then Range of functionf=domain of the inverse function

as Range of function f is[5,∞)

so the domain of the inverse function will be[5,∞)

03

Step 3. The Range of the inverse function

If a function fis one to one function

then Domain of function f =range of inverse function

As the domain of function f is [0,∞)

so Range of inverse function will be[0,∞)
