First, we need to find the domain of this equation

There are some rules about square roots, but this is the one we care about today:

**No square roots of a negative number**

So, we need to find the value of

*add #4# on both sides*

So,

Our domain is

Other than the shift to the right, our graph should look the same as the normal

graph{y=sqrt(x-4)}
