Answer:
its the first one
Step-by-step explanation:
In a quadratic function, the second differences are the same.
In the first table, the first differences are:
3-6 = -3;
2-3 = -1;
3-2 = 1;
6-3 = 3
The second differences are then:
-1--3 = 2;
1--1 = 2;
3-1 = 2
The second differences are the same, so this is a quadratic function.
