the table of values represents a function f(x)

  x               f(x)

  5                75

  6               202

  7               549

  8              1491

  9              4052

 10            11,014

 

how much greater is the average rate of change over the interval [9,10] than the interval [5,8]?

Rate of change  9 to 10  =    [ 4052 - 11014 ] / [ 9 - 10 ]  =  6962

 

Rate of change 5 to 8  =  [ 75 - 1491 ] / [ 5 - 8 ]  =  472

 

So  [  6962 - 472 ]  = 

 

6490
