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]?

 

X values:      2       3      4     5      6       7

F(x) values: 39   125  287 549 935 1469

 

Thanks for all of your help

avg rate of change over the interval [5, 7]   =   f(7)f(5)75

 

avg rate of change over the interval [5, 7]   =   146954975

 

avg rate of change over the interval [5, 7]   =   9202

 

avg rate of change over the interval [5, 7]   =   460

 

avg rate of change over the interval [2, 4]   =   f(4)f(2)42

 

avg rate of change over the interval [2, 4]   =   2873942

 

avg rate of change over the interval [2, 4]   =   2482

 

avg rate of change over the interval [2, 4]   =   124

 

How much greater is the avg rate of change over the interval  [5, 7]  than the avg rate of change over the interval  [2, 4] ? That is...how much greater is  460  than  124 ?

 

460 - 124  =  336

 

460  is  336  greater than  124 .
