Answer:
Find the domain for
y
=
√
x
−
1
so that a list of
x
values can be picked to find a list of points, which will help graphing the radical.

To find the radical expression end point, substitute the
x
value
1
, which is the least value in the domain, into
f

Select a few
x
values from the domain. It would be more useful to select the values so that they are next to the
x
value of the radical expression end point.
