Let f ( x ) = ( x + 3 ) ^2
Find a domain on which f is one-to-one and non-decreasing.

Find the inverse of f restricted to this domain
f − 1 ( x ) =

Using function concepts, it is found that:

-----------------

Suppose we have a parent square function:

-----------------

In this question, we have:

.

The domain on which f is one-to-one and non-decreasing is: .

-----------------

To find the inverse function on this domain, we exchange x and y, and isolate y. Thus:

The inverse function restricted to this domain is

  f(x) restricted to x in [-3, ∞) will have inverse function f⁻¹(x) = √x -3

Step-by-step explanation:

The given function is non-decreasing on the interval [-3, ∞), so that is a suitable domain.

The inverse function can be found from ...

  x = f(y) = (y +3)^2

  √x = y +3

  √x -3 = y

So, the inverse function of f(x) on the domain [-3, ∞) is ...

  f⁻¹(x) = √x -3

In the attached graph, the solid red curve is the domain-restricted portion of f(x). The blue curve is the inverse function. The dashed orange line is a reference line to help you see that the inverse function is a reflection of the function across that line.
