If linear or exponential or quadratic function to model a data set.
Answer to Problem 2E
If a common ratio exists among consecutive y-values, an exponential function must be used to model a data set.
Explanation of Solution
Given information:
If linear or exponential or quadratic function to model a data set.
Formula used:
The linear function must be model as data set.
Calculation:
If consecutive y-values have a constant first difference, a linear function must be used to model a data set.
If consecutive y-values have a constant second difference, a quadratic function must be used to model a data set.
If a common ratio exists among consecutive y-values, an exponential function must be used to model a data set.
Conclusion:
If a common ratio exists among consecutive y-values, an exponential function must be used to model a data set.
