Math Problem Statement

Below is the entire graph of function f. Graph f^{-1}, the inverse of f.

Solution

The graph you provided shows the entire function ff, and you are asked to graph f1f^{-1}, the inverse of ff.

How to Graph the Inverse:

To graph the inverse function f1(x)f^{-1}(x), you reflect the graph of f(x)f(x) over the line y=xy = x. For each point (x,y)(x, y) on the graph of f(x)f(x), the corresponding point on the graph of f1(x)f^{-1}(x) will be (y,x)(y, x).

Steps:

  1. Identify key points on the graph of f(x)f(x):

    • For example, if f(0)=2f(0) = 2, then f1(2)=0f^{-1}(2) = 0.
    • Similarly, if f(3)=5f(3) = 5, then f1(5)=3f^{-1}(5) = 3.
  2. Plot the points for the inverse:

    • Take several points from the graph and swap the coordinates.
  3. Draw the reflected graph:

    • After plotting the points, connect them in the same pattern but now reflected across the line y=xy = x.

Would you like me to provide a step-by-step breakdown of some points and their reflections for this graph? Feel free to ask for further details.

Here are 5 questions to expand on the concept:

  1. How can you confirm if two functions are inverses of each other?
  2. What properties must a function have for its inverse to be a function as well?
  3. What is the graphical significance of the line y=xy = x in finding inverses?
  4. Can all functions have inverses? Why or why not?
  5. How can you algebraically determine the inverse of a function if given the formula of f(x)f(x)?

Tip: Remember, a function must be one-to-one (each yy-value has only one corresponding xx-value) for it to have an inverse function.
