Well if you ask 30 people leaving the theater after an action movie, they will all probably say action movie. So, I think that a good answer would be a random group of 30 people at a mall.
Answer:
Option D
Step-by-step explanation:
Given
![(5, 7), (7, 11). (9, 14). (11, 18)](https://tex.z-dn.net/?f=%285%2C%207%29%2C%20%287%2C%2011%29.%20%289%2C%2014%29.%20%2811%2C%2018%29)
Required
Determine if the function is quadratic
![(5, 7), (7, 11). (9, 14). (11, 18)](https://tex.z-dn.net/?f=%285%2C%207%29%2C%20%287%2C%2011%29.%20%289%2C%2014%29.%20%2811%2C%2018%29)
Start by representing the function as an x-y table
x:- 5 || 7 || 9 || 11
y:- 7 || 11 || 14 || 18
Next; Calculate the difference between the values of y
![Difference: 11 - 7 = 4](https://tex.z-dn.net/?f=Difference%3A%2011%20-%207%20%3D%204)
![Difference: 14 - 11 = 3](https://tex.z-dn.net/?f=Difference%3A%2014%20-%2011%20%3D%203)
![Difference: 18 - 4 = 4](https://tex.z-dn.net/?f=Difference%3A%2018%20-%204%20%3D%204)
<em>The resulting difference are: 4 || 3 || 4</em>
Next; Calculate the difference between the difference of values of y
![Difference = 3 - 4 = -1](https://tex.z-dn.net/?f=Difference%20%3D%203%20-%204%20%3D%20-1)
![Difference = 4 - 3 = 1](https://tex.z-dn.net/?f=Difference%20%3D%204%20-%203%20%3D%201)
<em>The resulting difference are: -1 || 1</em>
<em>For the function to be quadratic, the above difference must be the same and since they are not, then the function does not represent a quadratic function.</em>
<em>Option D answers the question</em>
