Alright.... I will ask you this banal question, but please answer if you know (if you don't know just say so). What do you think,

I thought I gave enough information about how a parabola can open up/down, right/left in the previous question (and examples), but you don't seem to have read it..... I guess it is my fault that I didn't make it 'interesting' to read.....
