find the inverse of this graph on a table

Find the inverse of this graph on a table.

Solution

To find the inverse of the graph from the image, we need to create a table for the inverse function. An inverse of a function f(x)f(x) essentially swaps the xx- and yy-coordinates of points on the original graph. Let's identify some key points from the graph and then switch their coordinates.

Step 1: Identifying Points on the Graph

Based on the graph, we can estimate a few points:

  • f(0)=0f(0) = 0
  • f(1)1f(1) \approx 1
  • f(5)3f(5) \approx 3
  • f(10)5f(10) \approx 5
  • f(15)7f(15) \approx 7

Step 2: Creating the Table for f1(x)f^{-1}(x)

To find the inverse, we swap the xx- and yy-coordinates of these points:

f(x)f(x) (Original Function)f1(x)f^{-1}(x) (Inverse Function)
(0,0)(0, 0)(0,0)(0, 0)
(1,1)(1, 1)(1,1)(1, 1)
(5,3)(5, 3)(3,5)(3, 5)
(10,5)(10, 5)(5,10)(5, 10)
(15,7)(15, 7)(7,15)(7, 15)

Step 3: Interpretation

The table shows the points for the inverse function f1(x)f^{-1}(x), where the roles of xx and yy are reversed.

Would you like further clarification on how the inverse is constructed, or do you want to explore specific properties of the function?
