Answer 5

Are you familiar with the graph of \(y=\sqrt x\)?
It's a good one to memorize, the basic shape.

Answer 6

yes

Answer 7

So this is what \(y=\sqrt x\) looks like, yes?
Our function that they gave us has a +3 under the square root.
That represents a horizontal shift to the `left` 3 units.
