Inverse Function
 
 
Given the graph y = f(x), to sketch the graph of
                                         y = f-1(x)
reflect the graph of y = f(x) about the line y = x.
In other words, switch the coordinates: the point (4, 2) will become (2, 4) under the transformation.
 
Example: Sketch the graph of y = 1/(x+1) and its inverse.
 
Solution:
 
Graph of y = 1/(x+1):
