Exercises: Fit a Function to Data
Work through each section in order. When choosing a model family, justify
from BOTH the scatter plot's form and the context's mechanism. When using a
fitted function, substitute or solve carefully and state every answer with
units. Remember: a fitted model captures the overall trend — it need not pass
through every point — and predictions far outside the data range
(extrapolation) are not as trustworthy as predictions inside it.

Fluency Practice: Choosing the Model Family
For each scatter plot, decide which model family fits its form.
1.
The scatter plot below shows a bacteria count versus hours: the points stay low at first, then curve steeply upward, roughly multiplying each hour. Which model family best fits this data?
