A quartic regression model based on data for 0<=t<=2.5 predicts a maximum height of 18.6 at t=2.7. Which interpretation is most appropriate?
A
The measured maximum is definitely 18.6 at t=2.7; limitation: regression outputs are always observed data.
B
The maximum is invalid because all quartic models open downward; limitation: regression cannot locate extrema.
C
The model's maximum is 18.6 at t=2.7; limitation: t=2.7 is outside the data interval, so the prediction is extrapolated.
D
The maximum is 2.7 at height 18.6; limitation: time and height should be swapped.
