Answer
Refer to the image below for the graph (the black one).
Work Step by Step
Graph the parent function $ y=\sqrt{x}$.
(refer to the attached image below)
RECALL:
The function $y=f(x-h)$ involves a horizontal shift of either $h$ units to the right of the parent function $f(x)$ if $h \gt 0$, or $|h|$ units to the left when $h \lt0$
The given function has $h=-1$ therefore its graph involves a $1$ unit shift to the left of the parent function.
Thus, to graph the given function, shift each plotted point of the parent function $y=\sqrt{x}$ one unit to the left, then connect the points using a curve.
