You can tell if a function's inverse is a function if the y-values repeat themselves. This will be better illustrted with a drawing |dw:1406008355643:dw|

This graph has the same y-value for two different points. This doesn't pass the horizontal line test which is the test for an inverse.

so its true or am i just totally off haha

anonymous · Answer

(-1, 2), (1, 2) these two points have the same y-value of 2 so the inverse isn't a funciton
