===Graph of the inverse===
[[Image:Inverse Function Graph.png|thumb|right|The graphs of {{math|1= ''y'' = ''f''(''x'') }} and {{math|1= ''y'' = ''f''<sup> −1</sup>(''x'')}}. The dotted line is {{math|1= ''y'' = ''x''}}.]]

Reflecting across the diagonal is then necessary to have the axes in their natural positions.]]
