real analysis - Example of function f:mathbbRtomathbbR which is differentible and bijective but its inverse is not differentible.


Example of function f:RR which is differentible and bijective but its inverse is not differentible.





First of all do not know is above is true as for inverse function to be not differentible , there exist some point at which f(x)=0 which is not possible due to bijective ness .



Where I am missing ?



Any Help will be appereciated
