Question

How do you graph `y=-sqrtx` and how does it compare to the parent function?

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)`
