Question 1197653
.


If to consider your request formally,  as it is literally written, 

then the correct answer is  " No one of the given functions ".



        Why ?   -   Because the domain and the range are pointed  INCORRECTLY  in your question.



The correct writing is   " the domain  [-1,1]  and range   [0,pi] ".


Do you see the difference ?
