Answer:

Step-by-step explanation:

Draw a real or imaginary vertical line through the input (x-) value.  The corresponding output (y-) value can be read from the graph.  

For example:   If x = -2, we see that the vertical line x = -2 intersects the graph at y = 0, which is the output of this function when the input is =2.
