Ok I get the P669 question. Man I was confused… I never really gave that one a thought… I got hard questions right but its those medium questions that ALWAYS trip me!

Correct me if I am wrong for #8 on p652…

Here is my way since the lowest point is 1,1… the axis of sym has to be 1

I can assume that -b/2a

so 1= -b

-b = -1

therefore 1 = -(-1)
