Problem-Solving and Data Analysis practice question
A scatterplot shows a town's population every ten years from 1900 to 2000. The points rise slowly at first and then more and more steeply, with each decade's increase larger than the last. Which type of model best fits the data?
- A. An increasing exponential modelCorrect
- B. An increasing linear model
- C. A decreasing exponential model
- D. A constant model
Answer: A. An increasing exponential model
Increases that grow each decade are the mark of exponential growth.
Why the other answers are wrong
- B. An increasing linear model
- Linear growth would add the same amount each decade.
- C. A decreasing exponential model
- The population is rising.
- D. A constant model
- The population changes.
