Based on your description of the graph, here are the responses to the provided questions:
-
What interval shows a constant velocity over time?
Response: (0, 10) (assuming there is a straight line segment indicating constant velocity between these points). -
What interval shows the graph decreasing?
Response: (10, 15) (this refers to the sudden drop in the graph). -
After 20 minutes, what would the velocity be according to the graph?
Response: 40 m/min (after the drop, the graph rises again, but if you're looking for a specific value at 20 minutes, it seems to stay at 40). -
What is the domain for this function?
Response: [0, 60] (assuming the time starts at 0 and goes to the maximum of the graph which you stated is at 60). -
Is this linear or nonlinear?
Response: Nonlinear (due to the abrupt change and lack of a consistent slope).
So, the final answers based on your question setup would be:
- (0, 10)
- (10, 15)
- 40 m/min
- [0, 60]
- Nonlinear
