## 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 ?
