Answer:
It is 603 units greater
Explanation:
Given
See attachment for table
Average rate of change over (a,b) is calculated as:

For interval [7,9], we have:
![[a,b] = [7,9]](https://img.qammunity.org/2022/formulas/mathematics/college/zrdz68gs1umy1zhz7iwwx1cjpheq26r843.png)
So, we have:


From the table:


So:




For interval [4,6], we have:
![[a,b] = [4,6]](https://img.qammunity.org/2022/formulas/mathematics/college/150a0v9nuhsetvpzdy3bfynqn8dy2rob2z.png)
So, we have:


From the table:


So:




Calculate the difference (d) to get how much greater their rate of change is:
