    in fact we can find a formula for \[f(x)\] if you like you pick

    let's do the easy one you know \[2f(x)-3f(\frac{1}{x})=x^2\] so if you replace x by 2 you get \[2f(2)-3f(\frac{1}{2})=4\] and if you replace x by 1/2 you get \[2f(\frac{1}{2})-3f(2)=\frac{1}{4}\] which is the same as \[-3f(2)+2f(\frac{1}{2})=\frac{1}{4}\]

    so the basic idea is you are solving a system of equations like in algebra where you have \[2x-3y=4\] an d \[-3x+2y=\frac{1}{4}\]
