Factor it:

Solve for the zeroes:

Make a sign chart to see what the slopes are outside of those points. Graph to the best of your ability.

That's what I would do, Chad

Exactly! If the slope (the derivative) is negative, you know that the function is

meaning that it is falling as you move to the right.*decreasing:*

Similarily, the function isif the value of the derivative is positive.*increasing*

So, with a couple of points, and this knowledge, you can sketch a pretty decent curve!
