@satellite73 how do you become a moderator? It's been such a long time since I've been here :D why can't I fan you? The checking fan status thing is so slow :\

anonymous · Answer

increasing should be two intervals, not one
$$(-\infty, -4)\cup (-3,2)$$

anonymous · Answer

that is if i am reading it correctly

anonymous · Answer

does that make sense?

anonymous · Answer

see thats where im confused. it says i cant have a union for increasing

anonymous · Answer

then i am not sure what they want you to write
maybe put a comma between them? seems like a syntax problem

anonymous · Answer

i think the problem is maybe with how you are supposed to input the answer, not with the answer itself

anonymous · Answer

yep it was supposed to be a comma

anonymous · Answer

lol how'd i guess?

anonymous · Answer

and i got decreasing too, just missing the comma ha
