Which quadratic rule represents the data in the table?
X : -1 | 0 | 1 | 2 | 3
Y: 4 | 5 | 4 | 1 | -4
Y = -2x^2 + 5
Y = -x^2 + 5
Y = -x^2 - 5
Y = x^2 + 5
My answer is Y = -x^2 - 5

Or is it B?
well, geez - did you plug in the values?
y(0) = 5, so it will end in +5
1^2 = 1, so
y = -x^2 + 5
so, yes, B is the answer.
y(0) = 5, so it will end in +5
1^2 = 1, so
y = -x^2 + 5
so, yes, B is the answer.
