Math Problem Statement

The graph of f(x) is given. Determine the domain and range of f^{-1}(x) using interval notation.

Solution

To determine the domain and range of the inverse function f1(x)f^{-1}(x) from the graph of f(x)f(x), we need to remember that:

  • The domain of f1(x)f^{-1}(x) is the range of f(x)f(x).
  • The range of f1(x)f^{-1}(x) is the domain of f(x)f(x).

From the graph:

  1. Domain of f(x)f(x): The function starts at x=4x = -4 and ends at x=6x = 6. Hence, the domain of f(x)f(x) is: Domain of f(x)=[4,6]\text{Domain of } f(x) = [-4, 6]

  2. Range of f(x)f(x): The function ranges vertically from y=4y = -4 to y=6y = 6. Hence, the range of f(x)f(x) is: Range of f(x)=[4,6]\text{Range of } f(x) = [-4, 6]

Thus, for the inverse function:

  • Domain of f1(x)f^{-1}(x) (which is the range of f(x)f(x)) is: Domain of f1(x)=[4,6]\text{Domain of } f^{-1}(x) = [-4, 6]

  • Range of f1(x)f^{-1}(x) (which is the domain of f(x)f(x)) is: Range of f1(x)=[4,6]\text{Range of } f^{-1}(x) = [-4, 6]

These are the required answers in interval notation.

Let me know if you have any further questions or need additional details.

Here are five related questions:

  1. How do you find the inverse of a function algebraically?
  2. What are the conditions for a function to have an inverse?
  3. Can the domain of a function ever include infinity?
  4. What is the relationship between the graphs of a function and its inverse?
  5. How would the graph of the inverse f1(x)f^{-1}(x) look based on the given function?

Tip: When switching between a function and its inverse, remember to swap the x and y values!
