If 2*f(x) - f(1/x) = x2x2 , then f(x) is?	Choose the most appropriate option
A) f(x) = 3{2*x2x2 + (1x)2(1x)9 }	B) f(x) = 3{2*x2x2 + (1x)2(1x)2 }	C) f(x) = 3{2*x2x2 + (1x)2(1x)3 }	D) f(x) = 3{2*x2x2 + (1x)2(1x)4 }	E) f(x) = 3{2*x2x2 + (1x)2(1x)1 }
2*f(x) - f(1/x) = x2x2 ..............(1)   Take x = (1/x),   2*(1/x) - f(x) = (1x)2(1x)2 ...............(2)   Add: 2 (equation 1) + equation 2   3*f(x) = 2*x2x2+ (1x)2(1x)2   f(x) = {2*x2x2 + (1x)2(1x)2}/3   Answer:f(x) = 3{2*x2x2 + (1x)2(1x)2 }
