Q 1 If f(x) is a function satisfying f(x).f(1/x)=f(x)+f(1/x) and f(4)=65 , waht will be the value of f(6)...?
Ans: f(6) = 6^3 +1 = 217
Q 2 If f(x)=1/g(x) , then which of the following is correct? a) f(f(g(f(x)))) = f(g(g(f(f(X))))) b) f(g(g(f(f(x))))) = f(f(g(g(g(x))))) c) g(g(f(f(g(f(x)))))) = f(f(g(g(f(g(x)))))) d) f(g(g(g(f(x))))) = g(g(f(f(f(x)))))
Ans: c) g(g(f(f(g(f(x)))))) = f(f(g(g(f(g(x)))))).
