Answer:
None
Explanation:
- the slope has t to second power. So, the graph needs to be a parabola. Means second one is wrong.
- The slope is negative so the parabola is downward facing, so third one is wrong.
- When you plug in 0 for t, y becomes 80, so (0,80) point needs to be along the line. So first and second are wrong.
If first one was shifted letward so the vortex was at (0.80), that would be the correct option, but not how it is not.
