Question

The table of values represents a polynomial function ​f(x)​.

How much greater is the average rate of change over the interval [5, 7] than the interval [2, 4] ?

Answer 1

336

This is the correct answer! I just took the test! Good luck!

Answer 2

336

Explanation:

The average rate of change is Δy/Δx.

On the interval [5, 7]:

(1469 - 549) / (7 - 5) = 460

On the interval of [2, 4]:

(287 - 39) / (4 - 2) = 124

The difference is:

460 - 124
