Hi, I am having trouble in my algebra homework, I'm a freshman in high school. This is my question that im having trouble with, It's for a function machine. Ok, here it is, y = sqrt(x-5) if some can help me work it out hat would be great.

help work out what?

There are lots of questions you can ask about such a function.
Just what is it you want to know?

Maybe you could start by graphing it...
