Which quadratic equation fits the data in the table?
A. y = x² + 7x + 1
B. y=x2−7x+1
C. y=x2−7x−1
D. y=−x2+7x+1

a function could be identified in 3 ways either on a chart,graph, or ordered pairs. first a function is that each point has its own. the rule is that there can be many x's to one y but there can not be 2 x's at different y's. so on a graph when you put a straight line through the y's there should be one dot only to be a function.
