Answer: Check out the diagram below for the table and graph.
===========================================
Step-by-step explanation:
The domain is {2,3,4,5,6} which means these are the only allowed x inputs. Nothing else is allowed.
Plug in x = 2 to find that y = x-2 = 2-2 = 0.
Repeat for x = 3 to get y = x-2 = 3-2 = 1
This process keeps going until we go through everything in the domain mentioned. The outputs you should get are: 0, 1, 2, 3, 4 in that exact order.
The table is shown below. Each row represents a different (x,y) pairing and corresponds to a point on the graph.
Do not connect the points with a straight line. This because something like x = 2.5 is not in the domain. This graph is simply a disconnected set of points. It's considered a discrete graph rather than a continuous one.
