So the positive and negative is pretty straight forward isn't it? :O
On the left side of the x=1, the function is below the x-axis so it's negative on that side.

Do we need to write it in interval notation for the open box?

anonymous · Answer

ohh okay. yea

zepdrix · Answer

Does your assignment have special characters or anything?
If not, then I guess we could write something like `(-infty, 1)` for our negative interval.
Understand how to do similar for the positive?
