The difference between Tucker and Karly's take is that Tucker's solution is analytical while Karly's is graphical. But both are correct either way.
For Tucker's solution, let's say at x=-3 the value for y is 4, and at x=3, the value of y is still 4, then the average rate of change or slope is 0. Note that the slope of the curve is Δy/Δx. Since there is no change for Δy, the slope is zero.
For Karly's solution, even if the curve travels high or low but would have the same elevation of x=-3 and x=3, the average rate of change is still zero. It is actually just same with Tucker's but Karly just verbalizes her solution that was observed visually.

Answer:
She must have scored greater than 82 and up to 100 on the final
Step-by-step explanation:
Her average had to be between 77 or <= 85
for > 77:
(78+ 79 + 74 + 64 + 85 + x)/6 > 77
x > 82
for <= 85: (78+ 79 + 74 + 64 + 85 + x) / 6 <=85
x<=130 ( but she can only score up to 100)
