Translate the parent graph by

#### Explanation:

The parent function is

This trasformation belong to the family of the horizontal translations, which happens everytime you change from

In particular, you translate

In this case,

graph{sqrt(x) [-1, 20, -1, 5]}

graph{sqrt(x-1) [-1, 20, -1, 5]}

As you can see, the two graphs are identical, except for that
