Explanation:

First, let's take a look of the graph of #y=sqrtx#
graph{sqrtx [-10, 10, -5, 5]}
To graph #y=-sqrtx# we take the graph #y=sqrtx# and flip it over the #x-#axis.
graph{-sqrtx [-10, 10, -5, 5]}
In terms of the coordinates, we keep the #x# values as they are and negate the #y# value: #(x,y)->(x,-y)#
