These are yes or no questions. Read your book!

sorry, I know it seems like I'm not trying.
I was reviewing notes for a test tomorrow and in one section I wrote the first one and then right below it I wrote the second one. If I weren't so pressed on time I would find it in my book but I'm really trying to get finished and get a good nights sleep. D:

Remember this. y=x^2. Second derivative=2. x=0 is a min. y=-x^2. Second derivative=(-2). x=0 is a max.
