Homework Help: Simple but Unfamilliar Algebra

  1. Aug 17, 2007 #1
    This really isnt a homework question, but I figured its the best place for it.

    I have no idea what this means. It was posted on another forum I frequent. The poster said he is an accounting professor, and a student brought this up from another class. The problem is as follows:

    I think the X in the box just stands for f(x), and the two boxes stands for f(f(2)). But this is just an assumption.

    Thanks alot,

    Tanky322, you seem to be correct. The "box of x" must be "function of x". Use "2" and find the value of the function; then take this value and use it again as the value to use for x. The result is then f(f(2)).
