The quadratic function has no inverse function unless with restricted domain.
Explanation:
The quadratic function is represented by by the graph of a parabola(" U " shaped in this case), which is not a one to one function. To find if a function is one to one use a horizontal line test, if a horizontal line intersects the graph of a function in more than one point then the function is not one to one therefore it has no inverse function.
