For which of the following functions does f(−y)=−f(y) for all real number values of x?
Choose the correct choice from the following answers
A) y^8−y^4	B) y^2−y^6	C) y^5/y^7	D) y^9/(y^5+1)	E) -32/5 putting y=2 on y^5/(y^2+1)
all even root cannot be matched eliminated   put y=2   f(−y)=(−2)^5/(−2^)2+1=−32/5, and   −f(y)=−2^5/2^2+1=−32/5, for a match.   y^8−y^4NSWER: y^8−y^4
