I hope I am posting it in the right place! Here is the problem:
For which of the following function f is f(x)=f(1-x) for all x?
a) f(x)=f(1-x)
b) f(x)=1-x^2
c) f(x)=x^2-(1-x)^2
d) f(x)=x^2(1-x)^2
e) f(x)=x/(1-x)
I apologize if it is not posted professionally!
It is from GMATPrep software. Need explanation and how frequent are these type of questions since I have not seen them explained in any books.
