Draw a horizontal line ![\"\"](\"/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=6aac2b8aa96b8a5391692b8bb1e7735a.png\")
to the graph of the function.
![\"graph](\"/userfiles/image/Library/Trigonometry/graph_the_function_f(x)=(x)%5E(-2).gif\")
Observe the above graph :
\It is possible to find a horizontal line that intersects the graph of "f " at more than one point.
\So, "f " is not one - to - one function and does not have an inverse function. ![\"\"](\"/userfiles/image/steps_images/solution.JPG\")
No,the function does not have an inverse function.
