These tables represent a quadratic function with a vertex at (0,3). What is the
average rate of change for the interval from x = 7 to x = 8?

answer:

C

Step-by-step explanation:

Continuing the pattern on the right table, that is subtract 2, thus

Interval    Average rate of change

5 to 6                    - 11

6 to 7                    - 13 ← subtract 2 from previous value

7 to 8                    - 15 ← subtract 2 from previous value

Thus the average rate of change in the interval 7 to 8 is - 15 → C
