What math is this?

  1. Jul 3, 2010 #1
    We are studying linear equations in school and the prof gave us this to solve for extra credit:

    f(x+a) = f(x^2+a)
    what is x?

    I dunno what type of equation that is. Can anyone tell me?

    Edit: I posted in the wrong section... moving it now.

    Depends on what f and a are... are you given the function f? Or are you asked to determine a function f such that the relation you wrote down holds true for every x? Or something completely different?
