Math Problem Statement

The graph of a function is given. Graph the inverse function.

Solution

To graph the inverse function based on the given graph, follow these steps:

  1. Understand the Inverse Function Rule: An inverse function reflects across the line y=xy = x. The coordinates of each point on the function f(x)f(x) become (y,x)(y, x) for the inverse.

  2. Find Key Points on the Graph: Identify distinct points on the original graph and swap their xx- and yy-coordinates. For example:

    • If a point on the graph is (6,0)(-6, 0), the inverse will include (0,6)(0, -6).
    • If a point is (2,3)(-2, 3), the inverse will include (3,2)(3, -2).
    • Continue this for all identifiable points.
  3. Plot the Inverse Points: Use the new set of coordinates to plot the inverse function on the graph.

  4. Draw a Smooth Curve: After plotting the points, connect them to form the curve of the inverse function.

  5. Check Symmetry: Ensure the graph of the inverse function is symmetrical with respect to the line y=xy = x when compared with the original function.

Do you want me to assist you by plotting the points or verifying any part of this process?

Tip:
