$\text{the domain is the interval } [0,\infty)$
The radicand of the given function, $f(x)=\sqrt{x}-2 ,$ should be a nonnegative number. That is, \begin{array}{l}\require{cancel} x\ge0 .\end{array} Hence, $\text{the domain is the interval } [0,\infty) .$ Using the table of values below, the graph is determined.
