Consider the linear function with equation y = 3x + 5.
Sketch the graph of the linear function on the grid.
h t t p : //img402 . imageshack . us/img402/1466/picture38c . j p g
Here is a picture of the graph, and this is how I did it.
h t t p : //img9 . imageshack . us/img9/3918/picture41sg . j p g
Then it says.. Restrict the domain to the set of natural numbers. Mark the dots points on the graph which represent the function on the restricted domain.
I don't get how to do this.
