Could someone please teach me how to do this?

✰Answer:
0≤x≤1.
✰Step-by-step explanation:
To determine on which interval the function increases the most, we need to compare the average rates of change for each interval. The average rate of change measures how much the function is changing over a given interval.
Let's look at the average rates of change for each interval:
1. Interval 0≤x≤1: The average rate of change is 10. This means that for every 1 unit increase in x, the function increases by 10 units.
2. Interval 1≤x≤4: The average rate of change is 2. This means that for every 1 unit increase in x, the function increases by 2 units.
3. Interval 4≤x≤8: The average rate of change is 6. This means that for every 1 unit increase in x, the function increases by 6 units.
4. Interval 8≤x≤10: The average rate of change is -5. This means that for every 1 unit increase in x, the function decreases by 5 units.
From these average rates of change, we can see that the function increases the most over the interval 0≤x≤1. This interval has the highest average rate of change of 10, indicating the largest increase in the function for each unit increase in x.
Therefore, the function increases the most over the interval 0≤x≤1.
