Is your question to find all functions [itex]f:\mathbb{R}\to\mathbb{R}[/itex] such that [itex]f(x)+f(y^2)=f(x^2+y)\quad\forall x,y \in \mathbb{R}[/itex]?
If you want us to help you, show some effort. What have you tried so far?

Is the function defined on R or on RxR...?
Take some special values for x and y, like x=0, or y=0 or x=y and see where it takes you.
