Question

How do you graph `y=sqrt(-x)` and how does it compare to the parent function?

Answer 1

See the graph and the explanation.

Explanation:

The parent equation `y^2=-x>=0`, that represents a parabola, is

the combined equation for the pair

`y=sqrt(-x), y>=0` and

`y=-sqrt(-x),, y<=0`

representing the semi parabolas, in `Q_2 annd Q_3`, respectively.
