The problem involves finding a function f(x) and a constant a such that the equation 6 + integral f(t)/t^2 dt = 2x holds, with the limits of integration from a to x. This falls under the subject area of calculus, specifically integration and the application of the fundamental theorem of calculus.
The discussion is ongoing, with participants exploring different interpretations of the problem and suggesting potential forms for f(t). Some guidance has been offered regarding the use of differentiation and the fundamental theorem of calculus, but no consensus has been reached.
There is a question regarding the limits of integration, which are confirmed to be from a to x. The original poster expresses uncertainty about the approach to the problem.
