1. ## Help with MathAnalysis, please.

I need to find the domain of this function:

h(x)=[sqaure root] of 9x-27

Yeahh I don't know if you understand what I mean, but help would be appreciated. :]

2. The following is a true statement.
$\sqrt a$ is a real number only if $a \ge 0.$
Therefore, $9x - 27 \ge 0.$
