How do you graph #y=sqrt(x-3)# and how is it different from the parent function?

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]}
