Answer: the second one
Step-by-step explanation:
Answer:
We can see that as the endpoints of the intervals increase, the average rate of change for a square root function decrease
Step-by-step explanation:
Take for example the following intervals:
- interval: 0 - 1, average rate of change: √1 - √0 = 1
- interval: 1 - 2, average rate of change: √2 - 1 = 0.414
- interval: 2 - 3, average rate of change: √3 - √2 = 0.317
- interval: 3 - 4, average rate of change: 2 - √3 = 0.267
Answer:

Step-by-step explanation:
We are given the following in the question:
