Where are you having trouble with this?
They gave you the equation; plug in the numbers as specified (1, 2, and 6, respectively) and do the math (okay, you need a calculator for this one).
If you need more points to sketch the graph, then calculate more -- or use a graphing calculator. If you don't own one, search the internet; there are quite a few good ones available as free browser apps.
