If the function f (x) satisfies the relation f (x) 2F (1 / x) = 3x, then f (x)=

If the function f (x) satisfies the relation f (x) 2F (1 / x) = 3x, then f (x)=

We can replace x with 1 / X and put it in the condition
We know that f (1 / x) + 2F (x) = 3 (1 / x)
And f (x) + 2F (1 / x) = 3x
Elimination of F (1 / x) for simultaneous equations
We can find that f (x) = 2 / X-X
