Opening Exercise
What is this data table telling us?
Example 1
Remember that in Module 2, we used a graphing display calculator (GDC) to find a linear regression model. If a linear
model is not appropriate for a collection of data, it may be possible that a quadratic or exponential model will be a
better fit. Your graphing calculator is capable of determining various types of regressions. Use a GDC to determine if a
data set has a better fit with a quadratic or exponential function. You may need to review entering the data into the
stats application of your GDC.
When you are ready to begin, return to the data presented in the Opening Exercise. Use your graphing calculator to
determine the function that best fits the data. Then, answer some questions your teacher will ask about the data.
