The table of values represents a polynomial function f(x). How much greater is the average rate of change over the interval [7, 9] than the interval [4, 6]?

x   f(x)
4   105
5   384
6   945
7   1,920
8   3,465

9   5,760

Rate of change from 7 - 9 =    [5760 - 1920 ] / [9 - 7] = 1920

 

Rate of change from 4- 6 =   [945 - 105] / [ 6 - 4 ] = 420

 

 

1920 / 420    ≈   4.57 times as great
