Question

The piecewise function h(x) is shown on the graph. What is the value of X when H(x)=-3?

Answer 1

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.
