The problem is "Identify the quadratic function that contains the points (-1,1), (0,-2) and (2,4)." If someone could walk me through, step by step, it would be greatly appreciated. The answers are:
A. f(x) = + x + 1
B. f(x) = - x - 1
C. f(x) = - x + 2
D. f(x) = - x - 2

you are saying it as if a fact, not a question, but yes, you would be correct? ; )

step-by-step explanation:

127

whether it's diameter, or radius, i believe if i remember correctly from school, every amount has to always add up to 180. so if you take 53, and starting adding, long story short, taking 127 and adding it to 53, gives you 180.
