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
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)}
