A counter increases from 100 to 130 during a range with regular scrapes and no resets. Which function estimates the total increase over the specified range rather than a per-second rate?

1. increase(batch_processed_total[10m])
2. changes(batch_processed_total[10m])
3. avg_over_time(batch_processed_total[10m])
4. rate(batch_processed_total[10m])
