You take values for $x$ , preferably values that are a square +3.

Explanation:

In that case you'll get "easy" values for $y$
$x=3,4,7,12$ will yield:
$y=0,1,2,3$

This is an $x$ -translation from $sqrtx$ . The whole function is moved $3$ to the right, as now $x=3$ will give $y=0$
graph{sqrt(x-3) [-1.12, 18.88, -1.32, 8.68]}
