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]?

Avg rate of change  7 to 9   =  (5760 - 1920 ) / ( 9 - 7 )  =  1920

 

Avg  rate of change  from  (945 - 105 )  / ( 6 - 4)  =  420

 

1920 / 420  ≈   4.57 times as great
