Here's a problem that I am having difficulty doing:(adsbygoogle = window.adsbygoogle || []).push({});

1. The problem statement, all variables and given/known data

The question states:

if 2f(x)-3f(1/x)=x^2, determine f(2)

I am confused about the relationship between f(x) and f(1/x). My attempt right now consists of substituting y for f(x), 1/y for f(1/x) and 2 for the x in x^2 but i am quite sure that this is wrong since I do not get the answer that I was supposed to get (which is -7/4)
