Answer: I think the table has the greater rate of change because to find the greater rate of change we have to find the rate of change for both function. So, for this we have to find two points for both and then using the slope formula we have to solve for it.
for the first one: (4,6)(6,9)
9-6/6-4
3/2
For the second function: (4,5)(5,10)
10-5/5-4
5/1
5
so as we see that 3/2 is not greater than 5 so the function 3 has the greater one.
I don't know how to solve the first one. I am sorry but hope this helps you!
