f

is a real-valued function satisfying the relation

f(x)+2 f\left(\frac{1}{x}\right)=3 x

for all real

x \neq 0

, then

\lim \limits_{{x \rightarrow 0}}(\sin x) f(x)

is equal to

View answer and explanation

Correct option: B

Option B (2) is correct because by substituting 1/x into the original equation, we can solve for f(x) and then evaluate the limit.
