Writing Quadratic Equations Quick Check Determine if the following set of ordered pairs represents a quadratic function. Explain.
(5, 7), (7, 11), (9, 14), (11, 18)
(1 point)
The y-values go up by the square of the x-value (22 = 4). Therefore, the ordered pairs represent a quadratic equation
O Since the differences between the differences of the y-values is not consistent, the ordered pairs do not represent a quadratic equation
O
Since the differences between the x-values is 2 and the differences between the y-values is 4, that means that the differences between the differences of the y-values are all zero
quadratic equation
The y values go up by the square of the x-value (22 = 4). Therefore, the ordered pairs do not represent a quadratic equation
