and since they go in opposite directions, its either 5, 7 or 9?

  • zzr0ck3r
well not really, it looks like a cubic because it looks like the highest power in the long run. for this you need to see how many times it changes from decreasing to increasin and vice versa, this number will always be smaller than the degree
