[Jessica.c]

Ok so I am having trouble trying to figure out how to do this problem. Here it it: Find the domain. Show all work. Express answer in interval notation.
x/square root box x-2

I have absolutly no clue how I would even begin to start this out. Please help some one!

I have absolutly no clue how I would even begin to start this out.

Start with "All Real Numbers". There. Now you have a place to start.

Is it this? \(\displaystyle \frac{x}{\sqrt{x-2}}\)

If so, what do you know about denominators? Can the be zero? This may eliminate somthing.

If so, what do you know about square roots that produce Real Numbers? Can the be negative? This may eliminate something.
