Answer:
-1
Step-by-step explanation:
To find x for H(x) = -3, draw a horizontal line at y=-3. Where it intersects the graph, locate the x-coordinate of that point.
You will find H(-1) = -3, so the value of x is -1.
__
The graph has an open circle at (2, -3). This means H(2) is undefined. It is not -3.
