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]

The table shows 

x f(x) 

4 358

5  690

6  1178

7 1852

8  2742

9  3878

Rate of change on [7, 9]  =     [ 3878 - 1852] / [9 - 7 ] =  2026 / 2  =  1013

 

Rate of change on [4, 6 ] =  [ 1178 - 358] / [ 6 - 4 ]  =  820 / 2  =   410

 

So....the rate of change is   1013 - 410  =  603 greater
