Select the graph that best demonstrates the following trend:
A sprinter who runs at a certain speed (Y) and gradually gets tired over time (X).
The runner starts at a high speed and as time passes, he loses his strength and runs slower.
In other words, the graph will be descending, and therefore answer C is correct.
Is the function in the graph decreasing?
Look at the graph from left to right. If it goes up, it's increasing. If it goes down, it's decreasing. Think of it like reading a book!
When someone gets tired, their performance decreases. Since speed is on the y-axis, lower performance means lower on the graph, creating a downward trend.
A wavy or curved graph might show temporary changes, but for a sprinter gradually getting tired, we expect a steady downward trend over time.
The steepness shows how quickly the sprinter gets tired. A steeper downward line means getting tired faster, but any downward slope shows the right trend.
In theory, yes! If the sprinter gets completely exhausted, their speed could approach zero. The graph would show this as the line getting very close to the x-axis.
