It actually won't matter.
If you choose the wrong one,
you'll end up with the `negative` of the correct answer,
so just drop the negative.

As long as your intersection points are accurate, it should be ok.

haha I knew you would say that.
I know, it just bugs me now knowing which one is greater

points of intersection

zepdrix · Answer

Well, one option would be to run a `test point` which lies between your POI's, ya? And then compare to see which is larger.

Many books use the notation POI to mean "point of inflection". So be careful not to mix up the two ideas.

jim_thompson5910 · Answer

You can use a number line to break up the intervals, then plug in test values to see which is bigger (f or g)
