## Homework Statement

Ok, I just worked out a composite function, and it left me with:

√2x^2+5)

Now, how do I find the domain from that? I don't understand that my text says the domain of that is just all Real numbers ???

What makes this different than other square functions that we are able to find the domain like: √2-x ?
