Use the ray tool to graph g(x)={2x, x≥3; −13x+7, x≤3

See graph

Step-by-step explanation:

We want to graph the piece-wise function,

The two functions has a common point which is

.

Plot this point and one additional point on each line say;

and .

Click the ray tool and click the common point first and then click the second point to draw the first line.

Repeat the same process to draw the second line.

This will give you the graph that is similar to the one in the attachment.
