# What math is this?

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?
