How in the heck do I graph this?!

I have no clue how to graph this in a workable fashion.

$\displaystyle y=3^x$.

I do know how to graph other equations,(1) put the question into standard form if it isn't already, (2)replace the x or y variable(usually the x gets replaced), (3)work the equation to get y, (4)graph the point, (5)repeat steps 2-4 3 to 6 times, (6) connect the dots.

My problem is that the graph I am working with is fairly small, so the answers are either to high to graph or are decimals meaning that any attempt at accuracy is difficult.

Thank you!
