If f(x) = (x^2 - 1)/(x), what is f(1/x) in terms of f(x)? Choose the correct choice from the following choices
A) -1*f(x) B) f(x) C) 1/f(x) D) -1/f(x) E) 2*f(x)
f(1/x) = ((1/x)2 - 1) / ((1/x))   = ((1/x^2) - 1) / (1/x)   = ((1-x^2)/(x^2)) / (1/x   = (1-x^2)/(x^2)   = - ( (x^4) -1) / (x)   = -1* f(x)   -1*f(x)nswer is -1*f(x).
