If you're familiar with the graph of
f(x) = sqrt(x)
v(x) = sqrt(x) + 9 is going to be the same graph, but shifted 9 units upward.

depends
1. Are you graphing the function or, as you wrote, the domain of the function?
2. Is that (sqrt)x + 9 or (sqrt)(x + 9)?
3. If you have a graphing calculator, just enter it in y=. If not, then make a table: plug in numbers for x and find the corresponding values of v. Remember that you can not have negative values under the (sqrt) and still get real values for v.

the domain is x less than or equal to 9.
