SUMMARY

The discussion centers on solving the linear equation f(x+a) = f(x^2+a) for the variable x. Participants highlight the necessity of knowing the specific function f and the constant a to determine x accurately. The equation's nature depends on the definitions of f and a, indicating that without these parameters, a definitive solution cannot be provided. The conversation emphasizes the importance of context in solving mathematical equations.

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 don't know 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?
